Restoring state of an ADF component - oracle-adf

Jdev version :11.1.1.7.1
I'm iterating over a nested list and creating adf components at run time from my session scope bean based upon user input,Now the issue is i need to reset the panel group layout again in case user clicks on rest button and recreate all children based on a different user input.
The panel group layout is not getting reset even upon using :
either
searchResultPanel = new RichPanelGroupLayout();
or
searchResultPanel .restoreState(FacesContext.getCurrentInstance(), null);
Can anyone tell me how can i reset the state of panel group layout in my managed bean .

If you want to refresh panel group layout then you can remove its child components before adding the new ones, like:
pglayout.getChildren().remove(0)

Meteor + React - Social Network with graphic transitions

Context
I'm building a social network based on a parent/children relationship. It looks like a hierarchical pyramidal tree like this :
User Interface
Here is a first shot at the user interface :
The main part (big white block in the middle) is the user "wall" (as the facebook wall), with some specific fonctionalities.
The top home button is a link to the parent user.
The bottom buttons are links to children users
Navigation Animations / Transitions
I just discovered Meteor and React and feel now able to make the navigation awesome !
The idea is that when you click on a user button (parent or child), the button becomes the central wall div, a new parent user button appears from the top, old children buttons disappear and new children button appaears from aside. If needed, i'll try to make a gif.
The problem
User buttons and member wall are the same component with different state, "parent'/"current"/"child" with associated css class.
Clicking a children button or parent button will change the URL, we will go from "member/iduser1" to "member/iduser2". So the idea is to load the missing components and change the state of the ones already present on the page.
I can pass an array of children ids, the current id and the parent id to the wrapper in order to build the different components, but won't they be completly rebuild ? My goal is just to change their status

Conditional rendering of the bounded taskflow (jsff based)

I have page with three columns,details of each of the columns are as follows(in the attached image)
![Image showing column desc for the jspx page1
The use case is :I want to display one of the jsff's in the second &one in the third column based upon the tree node selected.
The approach i used is to generate a contextual event on tree node click with payload and a subscriber for the same for second and third column ,Now while trying to use the router to render the content conditionally,i'm failing .
The router gets invoked only for the time page loads and second time the control does not even go the router ,can anyone tell me what is that I'm missing here to achieve the use case.

Thanks.
Contextual events are done in the view so once the event hit the taskflow, your router will already been evaluated and your contextual event gets passed on to the current view.
It doesn't make the TF to initialize again.
Something you could do, it when the events triggers inside the TF view, you need to fire an action which points to the router.
So in your event handler you just navigate to your router.
Have a look at this one for navigation: https://blogs.oracle.com/jdevotnharvest/entry/how-to_navigate_in_bounded_task_flows
If you tree is in the parent jspx page you don't really need contextual events to manipulate taskflows. Just pass required data as taskflow's parameter and set Refresh property to IfNeeded for your taskflow binding to rerun your taskflow when its parameters changed.
If your tree also resides in taskflow and its sibling taskflow for details view then you indeed need contextual event, that should be catched at the parent jspx page (or taskflow) and then follow approach I've described earler with only change that parameter will come not from tree directly, but from payload of event.

Fuelux Tree: How to filter items based on status checkboxes

I have successfully implemented the FuelUx tree control but I want the user to click a different status check mark (IE active or archived) and only display the child items in the tree that contain the selected status.
Any suggestions on how to implement this feature?
Thanks,
Greg
My first inclination would be to add an active/inactive/archived/whatever class to the data source attr.cssClass key.

This would allow you to toggle which item state is being displayed at a given time. You could also use styles connected to the class to customize the icon based on the state.

Create disabled page property dynamicallyin a CQ page

I have a page X where I set a page property "type=myValue" using a drop down in page properties.
What I need is that when I create child page under page X, the child page should get the same property set for itself. This property should be disabled for end users to edit.
Can this be done without going through a workflow ? I need this to be set as soon as the page is created. ! Maybe some ext-js function on the child page template ?
Since you do not want to create a workflow, there are 2 other ways which are available through which this functionality can be achieved.
Creating an event handler that listens to Node Added event
Creating your custom servlet that handles the page creation activity by overriding the handler(CQ.wcm.SiteAdmin.createPage) for the Create Page button instead of the default command.
For quick reference, you can find details of implementing the event handler here.

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)
