"Property not found" with PrimeFaces RemoteCommand

I'm trying to update a Prime Faces PickList with a RemoteCommnad and I'm getting a javax.el.PropertyNotFoundException: Property 'updatePermissions' not found exception when the updatePermission property is defined.

This is my UI definition file:

<h:form>

              ...           

            <h:selectOneMenu id="groupsList" value="#{permissionsToGroupsBean.selectedGroup}" title="Select Group" onclick="updatePermissions()">
                <f:selectItems value="#{permissionsToGroupsBean.allGroups}" />
            </h:selectOneMenu>

              ....              

            <p:pickList 
                id="permissions" 
                value="#{permissionsToGroupsBean.permissionsPickList}" 
                var="permissionsPickList" 
                itemLabel="#{permissionsPickList}" 
                itemValue="#{permissionsPickList}" />

            ....

        </h:panelGrid>      

        <p:remoteCommand name="updatePermissions" actionListener="#{permissionsToGroupsBean.updatePermissions}" update="permissions"/>

This the controller that is supposed to handle the UI:

public class PermissionsToGroupsBean implements Serializable {

    ...

    public void updatePermissions() {
        getPermissionsPickList().setTarget(getPermissionsForSelectedGroup());
    }
}

When I access the page URL I get:

javax.el.PropertyNotFoundException: Property 'updatePermissions' not found on type tld.company.admin.web.bean.PermissionsToGroupsBean javax.el.BeanELResolver$BeanProperties.get(BeanELResolver.java:193) javax.el.BeanELResolver$BeanProperties.access$400(BeanELResolver.java:170) javax.el.BeanELResolver.property(BeanELResolver.java:279) javax.el.BeanELResolver.getValue(BeanELResolver.java:60) com.sun.faces.el.DemuxCompositeELResolver._getValue(DemuxCompositeELResolver.java:176) com.sun.faces.el.DemuxCompositeELResolver.getValue(DemuxCompositeELResolver.java:203) org.apache.el.parser.AstValue.getValue(AstValue.java:118) org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:186) com.sun.faces.facelets.el.ELText$ELTextVariable.toString(ELText.java:214) com.sun.faces.facelets.el.ELText$ELTextComposite.toString(ELText.java:155) com.sun.faces.facelets.compiler.CommentInstruction.write(CommentInstruction.java:77) com.sun.faces.facelets.compiler.UIInstructions.encodeBegin(UIInstructions.java:82) com.sun.faces.facelets.compiler.UILeaf.encodeAll(UILeaf.java:183)

Any help greatly appreciated, thanks.

Found it ... the problem was that Prime Faces doesn't handle comments for some reason ...

I had a commented out action listener defined under the one I posted in the question:

<p:remoteCommand name="updatePermissions" actionListener="#{permissionsToGroupsBean.updatePermissions}" update="permissions"/>

        <!-- <p:remoteCommand name="updatePermissions" update="permissions">  
            <f:setPropertyActionListener value="#{selectedPermissions}" target="#{permissionsToGroupsBean.updatePermissions}" />  
        </p:remoteCommand>  -->

As soon as I removed it it worked.

A signature with void return type and no parameters works:

public void updatePermissions() {
    getPermissionsPickList().setTarget(getPermissionsForSelectedGroup());
}

actionListener="#{permissionsToGroupsBean.updatePermissions}" Im not familiar with the current version of PrimeFaces but generally theactionListenerproperty would be expected to return an object that implements theActionListenerinterface. Thus your expression would be resolved togetUpdatePermissions()` which doesn't exist and thus you get that message.

If you added that method you should see that there's another problem with the return value not being an ActionListener.

Does the <p:remoteCommand> tag support an action property instead?
