dynamic view loading in custom directives' widget in angularJS - angularjs

I am using custom Directive's approach in AngularJS for making dashboard with widgets and for widgets m using angular-gridster
(https://github.com/ManifestWebDesign/angular-gridster).
Requirements:
On right side menu created by custom directive is present.and for routing purpose UI Router in used.
1-I need to open a dashboard firstly empty.
2-when click to Menu1 one widget is opened with data from state menu1 and same for Menu2
3-when 2nd option is clicked another widget added to dashboard without affecting previously opened one and so on.
4-all the widgets have independent data.and navigation in each widget is according to the respective menu.
WorkFlow:
1-empty dashboard is opened via custom directive.
2-widgets are added by providing click event to menu1 and menu2.which will broadcast event.and against that click event a widget is added to widgets array holding information about that widget.
Problem:
problem is routing basically.till now there is no routing involved.info is passed by broadcasting a click event.and by this i have achieved this coloured area.
but the further navigation creates problem.when a state changes by clicking Menu1 or Menu2 it affects both the widgets and and ui-view portion in both widgets show same data.if Menu1 is clicked both widgets show data from Menu1 and vice versa.
Now.i have tried enough solutions but here i want an idea from ui router experts or custom directives' experts.cz i hv tried many possible ways and stuck here for almost a week.
Thanx very very much if anyone can help.

Dynamic components in Angular 1.5.x

going beyond basics
To make it easier for people to understand what I am trying to do I made a simple plunker with a few components namely; cList, cListItem, cAddItem, cEditItem, cPanel.
The Controller passes an array of items (that it magically received from our data store) to cList component, which in turn renders each item.
Add New Item button supposed to initialise cPanel component when clicked and destroy? itself when the panel is closed or new item is created successfully.
Each item has an edit button which will initialise a panel with the item to edit. And just like Add New Item it should destroy itself when the panel is closed or item is updated successfully.
Simple CRUD, nothing fancy.
problems
I don't quite understand how I should invoke the panels in the first place.
If panels should be invoked from the Controller.
If it is possible to initialise and destroy panels on the fly.
If I should break cAddItem and cEditItem into separate modules instead (make it easier to handle display of panels?).
If my implementation of cPanel component qualifies it as a reusable component.
Could you help me develop my example to a working prototype, please?

How to hide a CQ component dynamically using Extjs?

I need to hide a CQ component from the page, when I select a particular value from another components dialog. Is this possible using ExtJS?
Yes, it is possible, but without more info it is difficult to give more details. In general, you can look up the xtypes you are using in your dialog at http://dev.day.com/docs/en/cq/current/widgets-api/index.html. Find the events that are available for the xtypes you are using in the dialog, then add a listener for one of the events exposed by that xtype. That allows you to run your own JavaScript code in response to an event--and that code could do things like hide HTML DOM elements.
Here is an example of using a listener to add custom functionality in response to an event: http://cq.shishank.info/2011/12/20/adding-limit-to-multifiled/
And here is another example: CQ5 - Hiding a tab within a component dialog depending on user group?

Angularjs two separate ui elements communicating

I have a use case to toggle the view of a form using a button. The button is not nested in the same structure of the form, and is out side the scope of the forms controller.
What is the best way to have this toggle button comunicate to the contents controller to display this content?
I have had a similar problem and for advanced comunications between controllers i would recomend a service. A service can be injected into multiple controllers so they can share information & state.
However if all your after is something like a button that you can place anywhere that will show the form, you could consider using the $location.path?
eg. on a view with a list of users
www.example.com/users
append edit
www.example.com/users/edit
then have the form controller watch the $location.path and open itself when it see's edit ?

Sencha Touch: TabPanel with bottom TabBar not working when using Stores

We're developing a simple app with the sencha framework
The app consist of a few tabs( a tabPanle with bottom tabBar) and the switching between tabs works perfectly when we use it as it is on the sencha docs, alas when no live data is present.
When we add stores within the single tabs, functionalities breaks, tabs stop switching and every time one clicks a tab to change the view, a flickering appears, the default tab is loaded again(from the chrome console we can see that all the remote data request of the loginView get reissued) and the only tab that remain visible to the user is tab[0].
app.js --> http://pastebin.com/S9qaNfij
mainView.js ---> http://pastebin.com/uiG2E0AW
controller.js ---> http://pastebin.com/8MTfxC85
This was created with senchaArchitect, that btw is awful and quite useless if not to work visually with the components.
here is a little movie of the thing happaning.

What are we doing wrong?
I think it's your button listener, it seems that it might be being triggered on even the tab panel button taps. I would try giving your button a unique ID and then create a ref and an action to login based on that ID.

How to create multi-page app with ExtJs 4

I should create ExtJs4 app, which should have main menu, and each menu item should open a new page with different url, so if the user copies the url and pastes on other browser tab, the app should open that menu item.
I want to use ExtJs's recommended MVC architecture, but I don't know how I can use it with multiple pages/urls. All their examples are using single page.
One option is to reload the page each time when the user clicks on particular menu Item, so every url/menu item/page will be separate ExtJS app with it's MVC. But I think this approach has drawbacks, since the page will be reloaded every time and it's not good for performance. Also it's causes difficulties in reusing of components (common models, stores and views for different pages ).
So I would like to have one single app for all pages, but I don't know is there any solution to have different urls for different views (in my case: for different menu items).
Or is there another approach for such applications?
You would probably want to use a Viewport, and make the Center Region a Container.
The Center Region Container would usually have a Card or Tab layout.
When the user navigates to a new view (Component), you add that view to the Container, and make it active.
The big mistake is to change the URL first. You don't want to do that.
You want to navigate, and then set the URL if the navigation was successful. You should probably not use ExtJS's History component, as it is incorrectly implemented. I would recommend using HTML5 pushState.
You should make sure your navigation system works without changing the URL bar too.
I would recommend reading up on Navigation in Microsoft Prism, WPF, and Silverlight, as there is more documentation there, and then apply that to ExtJS.
http://msdn.microsoft.com/en-us/library/gg430881(v=pandp.40).aspx
Here is an example Navigation process:
call app.requestNavigate('contacts/5'); you would add this yourself.
you parse this fragment to:
navigationContext = {
fragment: 'contacts/5',
xtype: 'contacts-form',
parameters:{
id: 5
}
}
OPTIONAL: If using forms:
get active item from the navigation region (your center region). if exists, call confirmNavigationRequest(callback) . you will need to add this method or event.
if callback(true), proceed with the navigation. this allows the user to cancel a navigation, if say the form is "dirty"
END OPTIONAL
the easy way is to then create a new widget of navigationContext.xtype, add it to the navigation region, then call setActiveItem(widget). destroy the previous active item if it existed.
then call history.pushState(null, null, navigationContext.fragment)
then raise a 'navigatedto' event on the view, passing the context, and you can load the data from there.
More advanced scenarios include:
keep the previous component alive if you expect to return to it. add a keepAlive property and if true, don't destroy when add new components to container.
search the container and ask each component if it wants to handle the current navigation request (for example if a form loaded with contact-5 was already hidden in your navigation region, or if you want to re-use a form)
