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)

in my app, when editing a record, I've added an ActionListener to save a temporary copy of the edited values for each field automatically, so that if the app is put in the background and then stopped, the edited values can be recovered when the app is started up again.
However, with the TextAreas it doesn't work since actionListeners don't get called unless the user takes some action (like leaving the field). I need to use the TextArea since there can be multiple lines of text, so using a DataChangedListener for a TextField as suggested in this thread does not seem a viable solution. And being able to save the TextAreas is important to achieve good UX since the user likely loses more work when text is dropped than if for example a value set in a Picker is lost.
Is there another way to achieve this result?
Thanks in advance
TextField allows multiple lines using setSingleLineTextArea(false). When invoked it will function similarly to TextArea.
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.
Here's my project folder if you need
https://github.com/guilhermeribeirodev/grizzlyboilerplate/tree/master/src/main/webapp/js/MyApp
I have created a form with a View as recordsource, this view combines 1 table and another view (with 2 tables in it).
When the checkbox is clicked a validation happens in the Access code that checks if the records checkbox may be updated, if this is not the case then the checkbox value should change back to 0/false.
First I tried to do this simply in the click event of the checkbox and then setting the checkbox value = false when it does not validate. This however gives a write conflict. Next I tried it with a Me.Dirty = false in front of it, this also doesn't help (still getting the write conflict). The checkbox.undo gives the same result.
Then I thought to do it in the before update and use a simple cancel=true, this however causes the focus not to change (it keeps the focus on the same record and never moves from it).
The Timestamp is usually what I use to ignore write conflict messages, I included the timestamp of the main table but this doesn't work (probably because the view is multiple-table based).
Some additional info:
The view is created in the SQL server and is linked to Access
The primary keys of the view (so it is editable) are set by executing a CREATE UNIQUE INDEX statement
Any ideas how I can get this to work?
Fixed it by using a button to set the checkbox bound field to checked/unchecked and making the checkbox itself invisible. This seems to work (better).
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 have an LOV added to my view object which updates 6 fields - done all through the LOV wizard in JDeveloper. It works perfectly fine when test running the application module - all fields update with the proper values after selecting a value from the LOV. However in my JSPX form, the only the field that gets updated is the one that the LOV is attached or is initiated on.
On my form, i only display 2 out of the 6 fields - the field which initiates the LOV and another editable field that the LOV is supposed to update. The part where this gets interesting is that the 4 other fields in my view object that i dont put in my form, are updated successfully by the LOV! But the one additional editable field that i left in my form, isnt updated.
Why is that?
I could just write a method in my View object Row Implementation class to update that editable field manually, but i feel like theres something more straight forward via declarative approach.
Thank you!
Fixed!
I needed to update two settings on my 2nd field of the form.
Removed the default bindings on the "Required" attribute and set it to "false".
Set "ShowRequired" to true
After that, I saved my changes and re-ran my application and the field updated properly!
I hope others find this helpful!
