list shuttle with dynamic source list

[seammm]

hi - i am trying to implement a drill down mechanism for the source list.

in order to do that i handle the dblclick as follows and try to get the selection.

------------------------------------------------------------
<rich:listShuttle id="sourceOrganization"
sourceValue="#{productHome.organizationSourceList}"
targetValue="#{productHome.organizationTargetList}"
sourceSelection="#{productHome.organizationSourceSelection}"
var="organization"
listHeight="300"
listWidth="300"
sourceCaptionLabel="All Organizations"
targetCaptionLabel="Selected Organizations"
converter="organizationConverter">

<rich:column>
#{organization.name}
</rich:column>

<a4j:support event="ondblclick" reRender="sourceOrganization"/>
</rich:listShuttle>


and i try to get the size of selection as follows.. once i get the source selection, and determine that it is a drillable category, i will refresh the source list, however size() always returns 0..

i will appreciate any help.. thanks.

public List getOrganizationSourceList()
{
try
{
log.info("ORGANIZATION GET SOURCE LIST CALLED WITH " + getOrganizationSourceSelection().size());
}
catch (Exception e) {}

return organizationSourceList;
}

just un update, i realized one needs to submit the form to get the selection values as stated in the demo.. however, i need to know the double clicked selection before the form submit.. so the user double clicks on source, i determine the item's type via a modification in ListShuttle.js and don't move it to target but i need to pass that item to back bean, via a4j:support and refresh the source. thanks.

"In order to set initially selected rows or to process submitted selection - use sourceSelection and targetSelection attributes."

I realize that sourceselection and targetselection attributes dont work. I can not get selection collection when submit. I want to process some thing when move, please review this problem. Many thanks.

xuantoan2510, are you sure that you have no validation/conversion errors?

[xuantoan2510]

I think my converter that is true because when i remove two attributes source selection and targetselection i still get sourcevalue and targetvalue.I add selection attributes i cant go to action method when click submit.
