Rich Tree

[sanghakanwar]

Hi,

We are using the richfaces tree control for building a tree based navigation. Is there any support provided for auto-refresh when a node is deleted from the tree ?

We were able to bind the node selection with the View on the right side , but when we delete the child node , is there any way to refresh only the opened tree parent node ?

Thanks,
Kanwar

Hi,

You could bind your entire rich:tree with UITree component from richfaces package. For example.

Create a seam component UITreeBean of SESSION scope. Define a org.richfaces.component.UITree member with it's getter and setter and finally binds your rich:tree with this member. So every change you make in your tree it's gonna be reflected in your page.

<rich:tree binding="#{uiTreeBean.yourUITree}" />

Thanks for your reply.

The tree should work like a windows explorer. When i delete a node on the right side of the screen, the node which was shown in the tree should automatically get deleted.

All operations (add/delete) happen in the right frame and not on the tree component.

Example -

Tree Frame     View Frame
----------------------------------------
Root          root1 page will be shown when
             "root1" is selected from the tree
   - root1
   - root2
           
----------------------------------------

Now if i delete root1 from the delete action in the root1 View Page,how does the root1 in the tree get deleted ?

Hi,
What about remove/add node by code in your delete/add action and refresh your tree frame. Or you could use DIV's instead of frames, things would be easier i think.

If we refresh the tree frame, the state is lost. If i had some parent nodes open, it just collapses all...we need a way to save the current start and only refresh the opened node...
