Summary: Picklist : valueChangeListener does not work when user moves items
between left and right sides
Key: RF-12053
URL: https://issues.jboss.org/browse/RF-12053
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-selects
Affects Versions: 3.3.3.Final
Environment: RichFaces 3.3.3Final
JBOSS EPP5.1.1
browsers : Firefox 10.0.2 and IE8
Reporter: Andrew Cheung
The valueChangeListener for picklist does not fire when a user moves items between the
left and right hand sides of the picklist.
Code as follows:

copyAllVisible="false" removeAllVisible="false"
value="#{myBean.selectedAuxOffices}" converter="sibcvtr"
valueChangeListener="markAuxOfficesModified" >
<f:selectItems value="#{myBean.auxOffices}"/>
</rich:pickList>
<h:commandButton styleClass="btn-go" id="btnSubmit"
action="#{myBean.modifyUser}" value="Go" />
</a4j:form>

-------------------------------
Forum Reference: https://community.jboss.org/message/628865#628865 (was:
https://community.jboss.org/message/628865#628865)
I found an explanation to the behaviour: Moving items between the left and right hand
side are client side and therefore the event is not triggered. The event is triggered on
submit.
To the administrator of bug reports : Please cancel this bug report. Thanks.
Picklist : valueChangeListener does not work when user moves items
between left and right sides

Resolution: Rejected
Not a bug. It was due to the user's misunderstanding of the behaviour.
