[richfaces-issues] [JBoss JIRA] (RF-10992) dragValue expression is evaluated to null in customcomponent

[ https://issues.jboss.org/browse/RF-10992?page=com.atlassian.jira.plugin.s... ] Brian Leathem updated RF-10992: ------------------------------- Fix Version/s: 4.Future (was: 4.1.0.Final) Description: When the dragValue is set in a customcomponent, it's always evaluated to null. (dropEvent.getDragValue() == null) If a stringvalue is set instead, the value is submitted correctly. Example: {code} <rich:dragSource type="sometype" dragValue="#{cc.attrs.myvalue}"/> {code} same code outside of the customcomponent works fine. was: When the dragValue is set in a customcomponent, it's always evaluated to null.

Example: <rich:dragSource type="sometype" dragValue="#{cc.attrs.myvalue}"/> same code outside of the customcomponent works fine. Steps to Reproduce: create a customcomponent like the following: {code} <composite:interface> <composite:attribute name="myvalue" /> </composite:interface> <composite:implementation> <h:form> <a4j:outputPanel> <rich:dragSource type="sometype" dragValue="#{cc.attrs.myvalue}"/> ... </a4j:outputPanel> </h:form> </composite:implementation> {code} and a <rich:dropTarget ... somewhere else. was: create a customcomponent like the following: ... <composite:interface> <composite:attribute name="myvalue" /> </composite:interface> <composite:implementation> <h:form> <a4j:outputPanel> <rich:dragSource type="sometype" dragValue="#{cc.attrs.myvalue}"/> ... </a4j:outputPanel> </h:form> </composite:implementation> and a <rich:dropTarget ... somewhere else. Labels: customcomponent (was: customcomponent draganddrop needs-qe richfaces) Assignee: (was: Brian Leathem) Component/s: third-party Looks like the problem stems from upstream with JAVASERVERFACES-2009/MYFACES-3283: {quote} The main problem is that if you reference a property of child component anywhere outside of the composite (i.e. in an action method, a component system event, etc.), it simply will not work if it was set to a composite component attribute (i.e. _#\{cc.attrs.property}_). {quote} Confirmed by taking the _dragValue_ assigned to the composite component, and applying it directly to the _dragSource_ (iow not using the _cc.attrs.dragSource_ peroperty), and the metamer sample works. Feel free to comment/vote on the upstream issue, to see it resolved. -- This message is automatically generated by JIRA.
