Nick Belaevski commented on RF-2393:
------------------------------------
Mike,
Can I ask you for a simpler test case? The one attached is somewhat complicated
for investigation and debugging and will take a lot of time.
> Tree nested inside node of an outer tree has strange behaviour on ajax submit
> when there are validation errors
> --------------------------------------------------------------------------------------------------------------

> Key: RF-2393
> URL: https://jira.jboss.org/jira/browse/RF-2393
> Project: RichFaces
> Issue Type: Bug
> Affects Versions: 3.1.4
> Environment: Glassfish v2, JSF RI 1.2
> Reporter: Mike Hanafey
> Assignee: Nick Belaevski
> Attachments: NestedTree.tar.gz, NestedTree.war
>
>
> I have situation where there is an outer tree whose nodes have an inner tree.
> Specifically, the outer tree is over DNA sequences, and each DNA sequence may
> have a tree of comments attached to it.
> Both the inner and outer trees have a couple of faces, one is used when a
> node is in display mode, and the other when it is in edit mode.
> If the inner tree is put into edit mode at a node (via an ajax request) and a
> validation error occurs on a second ajax request to submit the edits, the
> whole inner tree for that node disappears. It can be recovered by doing a
> browser redisplay. If there is no validation error, the edit works as expected
> Looking at the XmlHttpRequest response when there is a validation error shows
> that the response does not contain the expected tree nodes.
> When this same comment tree code (both the backing beans and the facelets
> views) is applied on an unnested tree this problem does not occur.
> A test war is attached (the war is big only because it includes the library
> dependencies -- the test code itself is small).
> To demonstrate, deploy the war and look at the top page.
> Click on the + next to "Comments" (this is the un-nested tree). Click "Ajax
> Save". Observe the "Value is required" messages.
> Enter something into the first textfield, and do the "Ajax Save". Now a
> custom validation message appears.
> Now for the first strangeness. Enter something in both the textfield and the
> textarea. The custom validation message appears on both inputs, but now the
> inputs just made are erased. When only one of these fields have data, the
> data entered in the other field is preserved, and I believe the clearing of
> input data is another error, but not the one in the title of this this issue.
> To see the main issue, open the tree labeled "Sequences". This has a comments
> tree just like the one above nested inside the sequence node.
> Click on the + next the "Comments" under "Sequences".
> Click on "Ajax Save". Now instead of seeing the "Value is required" error,
> the inner tree node collapses. Click on the "Submit" button, an reopen the
> "Sequences" tree to see that the inner tree is in fact still intact.
> Click on "Ajax Immediate". Now the tree does not collapse. The only
> difference is this button is immediate, so the validation steps are not done.
> Finally, clicking on "Plain Save" shows the expected validation errors (now
> the Sequence tree collapses after the submit so it must be manually opened,
> but I guess this is expected behavior because the open / close state is not
> maintained across the request). The problem where the inputs that fail
> validation are erased remains even with this non-ajax update mode).
