-------------------------------------------
Hallo Cagatay,
Thanks for getting on to this.
My assessment of the problem is the following (using Chintans's code from
above):
<s:selectManyPicklist size="10" style="width:175px;"
valueChangeListener="#{accessDelegationController.selectionChangedForOperations
}"
value="#{accessDelegationController.selectedOperationsList}"
immediate="true">
<f:selectItems
value="#{accessDelegationController.operationsList }" />
</s:selectManyPicklist>
Observation:
The first time that the picklist is rendered, both the value method
#{accessDelegationController.selectedOperationsList} and the selectItems value
method #{accessDelegationController.operationsList } are called. -> Up to the
point where the form is submitted for the first time, the preselected values
are actually working.
And now the problem:
After the form in which the picklist is located has been submitted, the value
method #{accessDelegationController.selectedOperationsList} is never called
again whereas the selectItem value method is called after every submit. Thus
the preselected values don't work after the first submit.
Hope this helps - I'm dying for a fix!
Cheers,
David.
