Hi Björn,

the popup menu crashes when the list of menu items is empty.
The attached logfile is missleading because the jsp is correct (the designer can read it and it works if there are menu items added).

<t:popupmenu id="STATUS_COMMANDS" componentbinding="#{d.cardproductionList.commandPopup}" rendered="#{d.cardproductionList.showCommandPopup}" />

You find the server side code in the second attachement.
I try to render the popup menu only if the children list contains menu items.

Hi Frauke,

I tested - no problem on my side:

Code:

     public void setMenu(POPUPMENUComponent value) 
     { 
         if (m_menu == value)
             return;
         m_menu = value; 
         m_menu.getChildren().clear();
         
         if (isMenuRendered())
         {
             MENUITEMComponentTag mict = new MENUITEMComponentTag();
             mict.setText("Menu A");
             m_menu.getChildren().add(mict.createBaseComponent());
         }
     }
     
     public boolean isMenuRendered()
     {
         return false;
     }

and the layout

Code:

 <t:rowbodypane id="g_5" popupmenu="TEST" >
 </t:rowbodypane>
 <t:popupmenu id="TEST" componentbinding="#{d.DynPopupMenuUI.menu}" rendered="#{d.DynPopupMenuUI.menuRendered}" />

Are you sure that your nice method m_rows.getSelectedItem().isLocked() is never stopping with a null pointer, e.g. if you do not have any selected items...? ;-)

Hi Björn,

the problem was that I used
m_menu.getChidren().isEmpty()
in the render function, and the render function was called before setMenu() and so the m_menu was null.

Thank anyway....
