Hi Tom,
You can also do some customization and it should work with your version also:
You need to change this action :
pdmObject-actions.xml ->
<action name="SETSTATE_FROMFOLDERS" selectRequired="true" multiselect="true" checkaccess="true" enabledwhensuspended="true" renderType="PDM" uicomponent="SET_STATE">
<command windowType="popup" class="java.lang.Object" method="SETSTATE_FROMFOLDERS" onClick="validateSomethingSelected(event)"/>
</action>
I changed this action and added it to the custom-actionModels.xml and "Set State" works with multiple selection.
Regards,
Vytautas
