[richfaces-issues] [JBoss JIRA] Commented: (RF-2393) Tree nested inside node of an outer tree has strange behaviour on ajax submit when there are validation errors

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).
