Question

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)

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());
}
