tree2 broken?

[Andreas Schenk <dr...@gmx.net>]

Hi,

it seems to me that the state saving mechanism of tree2 is broken:

As I wrote earlier today in another thread, tree2 with client side toggling 
does collapse completely when a leaf is clicked, if URL rewriting is used to 
track sessions. 

Thus I switched to cookies and ran into another problem: When I change the 
tree structure the application dumps. However, when I delete all cookies on 
the client side and try again, all works well. It is not straight forward to 
reproduce this behaviour as it depends on how the tree structure changes. 
Some changes do not cause the app to dump, others do.

Note that I didn't change the tree structure dynamically in the web app; I 
just changed it in the code and redeployed the application. I would guess -- 
but I don't know -- that the problem is worse if the tree structure is 
changed dynamically by the web app itself.

What will happen, if more than one tree is present in one web app, or even in 
one page? What, if framesets are used in addition? 

Regards

Andreas Schenk

I'm getting the duplicate id problem also. I'm using the latest (sept. 8th) 
nightly build and that didn't fix the problem. Bala, did you get past your 
duplicate id problem?
 Thanks for any help,
Jeff Cooper

Ah,

Your explanation gives me the solution for the BitMask. 
Thanks

The invalid bitmask comment comes from HtmlTreeRenderer.  This basically
means that the renderer encountered an unexpected condition.  In the
case of a bitmask of 6, this means the renderer thinks that the node is
expanded but yet it has no children.  Only nodes with children should be
expanded.

Most likely you are providing your own TreeNode class and it is
providing the wrong answer to the isLeaf() method.  Either that, or you
are supplying the wrong data to TreeNodeBase.

I didn't check MYFACES-404 or MYFACES-423. I mean that the application throws 
an exception. I can manage to get either of the following two:

javax.servlet.ServletException: cannot add component with id '_id77' and 
path : {Component-Path : [Class: 
org.apache.myfaces.component.html.ext.HtmlGraphicImage,Id: _id77]} to its 
parent component. This might be a problem due to duplicate ids.

javax.faces.FacesException: Invalid bit mask of 6

I have a simple page, containing the tree2 example with both, server-side and 
client-side toggle. I open both trees, delete a node from the TreeBacker, 
redeploy the application and reload the page with the browser.

Andreas Schenk

What do you mean with the application dumps?

This issue might be fixed with MYFACES-404 and MYFACES-423.

Open a JIRA issue on this one.  I believe there are a few problems
with the new TreeState interface.  I will look into it later this
week.
