[richfaces-issues] [JBoss JIRA] (RF-11617) rich:pickList 4.1.0.M3 - valueChangeListener not firing correctly

[Brian Leathem (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-11617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643102#comment-12643102 ] 

Brian Leathem commented on RF-11617:
------------------------------------

Indeed, there does seem to be two issues here:
1) The listener of your _a4j:ajax_ tag is not being fired.  Could you please file an issue for this?  It's defeinitely worth digging into.

2) {quote} Firing the VCL
I noticed that when I click the add control the setter is called for the
pickList value= attribute, so the value has changed
{quote}

The setter should not be called here.  In the current impl, the VCL isn't fired, and the vaule shouldnt' be updated, until the component loses focus.  This is to account for a user making a sequence of mutually annihilating changes, when the value isn't in fact changed.  If you notice the setter is being called, then this is incorrect behavior.

Does this setter still get called if you remove the nested _a4j:ajax_ tag? I imagine not, but I just want to be sure.

> I have two List<String>, selectedList & wholeList. Using the add/remove(all) buttons
