I have a page with two panels. The first panel is where create and update happens, and the second panel is a list of stuff that I just added. Sort of like this (below). The second panel updates the list every X second.
Each list has an edit button that takes it back to the first panel. I pass the entity through the button's function and fill up the values in the edit panel. Here's the weird thing, when I try like say edit an entity in the list, an the interval happens to update the list, the entity gets refreshed and all my changes are never saved.
I tried just passing the id though the button then doing a get request for that particular entity and performing the edit, but the interval takes place and my changes are reverted.
I think my only option is to do angular.copy(myEntity) and do the edits from there, and then manually do the PUT request. Is there another way for the edited entity not to be affected by the interval aside from doing an angular.copy()? Pausing the interval while something is being edited is not an option, since client wants the list to update even when he's editing something.
If you need to keep your data up to date by refreshing every few seconds, i recommend implementing a bool HasChanges() function in your controller. This will return true if the data has changed, and false if not. That way you can decide if you want to pull and refresh new data, or deffer it until your editing is done without overwriting your unsaved changes.

I'm using ExtJS 5.1.3, I have a grid which is loaded from a store which has a model. The grid is set to use plugin roweditor, so I edit a cell and give it a new value, at this point the red tick is shown that the cell has been changed.
I have a Save button which when clicked gets the store.getModifiedRecords() and passes these off to a ajax request, upon success of this request a few things happen and the last action I do is to load the grid store again which then populates the grid again with the latest version of the data, this is fine and seems to be working as expected.
As this is a multi page application I also have a check when a user navigates away from this page, this is to catch any unsaved grid changes, so basically I get any form from the page and verify the isDirty() value, this is where I am finding my issue, the roweditor is being returned as dirty, this is because some columns have an editor and ExtJS uses form validation on these fields,
I can't understand why the store loading again has not cleared any dirty fields associated with the grid columns? I've tried a number of things such as clearing the store prior to ajax request along with refreshing the grid view, I've tried committing the store changes prior to doing the ajax request but each time I try navigate away from the page after a grid save I pick up the roweditor as having dirty fields :( any help is greatly appreciated.
EDIT: managed to replicate on a simple fiddle
https://fiddle.sencha.com/#view/editor&fiddle/1rmf
The fiddle is basic, to replicate follow these steps;
edit first row age, change age to 13
click Save (i'm forcing the store to load data which has the change we've made)
click 'Check roweditor is Dirty() value' button to see the value of the roweditor isDirty() function, this will return true
if you look at the button handler, you can drill into forms[0].items.items[2] and see that this field has dirty: true which is why isDirty() is returning true.
SOLUTION
As explained in accepted answer, the roweditor is not affected by the store edit/cancel or load in my case. What I did when clicking on 'Save' was to get the grid, then the editor and it's form and called reset() on this so effectively sync everything again.
grid.editingPlugin.getEditor().form.reset();
you can also get access to plugins via grid.getPlugins() which returns an arrary
updated fiddle to show it working

During the editing process grid will eventually call loadRecord on the editor's form. However the editor's form is not cleared upon editing success or canceling. That is why your check for dirtyness returns false.
Grid reloading the data is not destroying the editors. It is an optimisation. Editors are created only once and they are destroyed along with the grid.
I'll try to answer regarding to an experience of mine with an all ExtJS desktop application.
By the way looking quickly over your description, you may have to call the Store.sync() method that refreshes your store.
Looking more deeply, there are many way to make CRUD using ExtJs.
I've been made using the "instance" of store but at certain point I had to change it to static calls like MyApp.store.Model.save() etc. That makes you have only one instance of the store avoiding dirty data.

I have a problem with Angular UI-Grid (http://ui-grid.info/). Grid is implemented in modal window that appears after user clicks button.
Service works that way: User selects data set to prepare and clicks button. After clicking button website sends request to rest service to receive data. After receiving data modal with table is shown. Columns count depends on data requested by user.
The problem is that after user changes columns width and close modal with this table UI-Grid 'remembers' this column width that user left. If then user will select another set of data I am cleaning GridOptions object and fill it once again after data is received. The problem is that row width stays in previous state.
I tried so far:
using apis core.refresh() method - while debugging I can see that this
method fires some event but no effect on my grid,
remove whole DOM node and append it again before receiving response with new data
various different hacks trying to use many methods found inside grid api - no success at all.
I am sorry that I am unable to reproduce this in any fiddle but it would be really difficult I am afraid to match my case.
Any help would be very appreciated. Thanks
ps. it also applies to my another table where user can pin and hide columns. Pinned/hidden columns remains hidden/pinned after receiving brand new data. And it is not cool.
Once you set the data to the grid, you should be calling this -
gridApi.core.notifyDataChange( uiGridConstants.dataChange.ALL)
From the docs,
Notifies us that a data change has occurred, used in the public api
for users to tell us when they've changed data or some other event
that our watches cannot pick up
notifyDataChange tells the framework that one of the options or columnDefs has been changed.

I need to allow or stop an event from happening, based on a given condition such as a pop up box with options YES, NO and CANCEL.
I need to notify the user saying that there are unsaved data and if the user wishes to SAVE it, IGNORE it or CANCEL his current action(event such as Selection-change or Click).
I tried to use createInterceptor() function. But could not achieve the functionality.
Can anybody give me some suggestions with example? Basically I want to know how to stop an event.
Thanks..

I like the idea of using beforeXXX events. But I am still facing problems. As I mentioned, I need to ask the user if he wishes to save the unsaved data, which is a popup message box (With options YES, NO and CANCEL) that runs asynchronously. So by the time I get a reply, the event will have happened.
For ex. lets imagine a situation where, there is a page that displays a list of records in a grid with a pagination toolbar attached to it on the bottom(with a page size of 10 and total number pages is 10. So totally 100 records) on the left hand side. If you select a record in the list, the details are shown in a detail view on the right hand side.
Now,
I select third record in the list and make some changes to it in the detail view(form).
Without saving the record, I click on next page button on the Pagination toolbar.
It will show a confirm box from the beforeXXX event of Pagination toolbar, but the event will have happened anyway.
Here if the user clicks on CANCEL, I will have to restore the previous state which is already gone. Somehow I will have to go back and select the third record in the list of previous page.
So in order to resolve this problem, if I return false from my beforeXXX event, the next XXX event will be not be triggered.
But if the user clicks on YES or NO options I will have to trigger the event XXX manually which I am unable to do it for a selection-change event as of now.
Like this there can be many operations like list-filtering, searching, Ordering(A-Z/ Z-A), logout etc. For each of this operation I will have to write customised code which totally spoils the readability of the code.
So I was thinking if there is way to, somehow manually trigger the event XXX by holding the event object in beforeXXX...or is there any other way to restore the previous state.
Please give me suggestions....Thanks...
Many events have their "before-" counterpart, for example "beforeactivate". If you return false from this kind of the processing stops.
If not, or if your event does not have it's before- part, then you can use event object passed to all event handlers and call:
ev.stopEvent();
ev.stopPropagation();
return false;
at the end of your handler.
In my sencha touch 2.3 app, I have a page that has few toggle fields, text fields etc. I want to set values on these fields every time the page is shown (it might have different set of values every time).
The parent container of this page is a panel that has card layout. I show the different pages using setActiveItem('pagextype');
Now, if I set values during initialize, it will get set once, but the next time the page is shown, initialize will not be called. And the elements will not be set to the new values.
Instead of initialize, I used painted event. This works fine. But whenever I go to the page, for a moment it displays the old values and then updates itself to the new values.
What is the best way to handle this scenario?
You can follow below steps.
Store data in some array or any object(let say OBJ) during initialize().
Create a method updateData(index),which is responsible for updating data in the card layout element on the basis of index.this method is called from activeItemChange event function,which is called whenever there we swipe the item in card.
Now by default index 0 item on card layout is shown.
when we swipe,activeItemChange for the next item is called,you can write your logic inside updateData() method to update the data from the initial array/object(OBJ) on the basis of index.
We have a rowediting plugin on grid where a button of one trigger field changes some other values of the record (we are loading some remote data which get applied to the record). The values that get changed in background are most commonly not editable, so they are just rendered. Basically the remote loading of the data works fine, meaning the record get changed and all data get save but we have the following problems:
1.The rowediting plugin does not show the changes that where applied to the record fields
2.Setting the changes via record.set() cause the store to sync immediately and not on clicking the "save" button of the editor.
So how can we make the editor to show the changes applied in the background and how can we apply these changes in a way so that they get saved along with the other edited fields.
Thanks in advance for any help!
This should not be that complicated, you just need a reference to your active editor instance. You can then either
reload the record into the form by calling loadRecord() again. But note that this may overwrite any changes that where made by now within the editor
or (for the second way I expecting the values to be exactly the same as in the record in manner of key:value definition - short: no special mapping is required)
apply the new data to the record by calling either set (note that this will trigger sync if you have autoSync turned on) or by using Ext.apply(recinstance.data,newvalues) and editorinstance.getForm().setValues(newValues)
