    Tree click event is fired out of sequence

    Srikanth Chakravarthy Newbie

      Hi,

      I am using Richfaces 3.3.1 and the component in discussion is Rich:Tree. I use a dynamic way of building the tree and am using a custom view handler extending the FaceletViewHandler. I use java classes to create the component and provide the viewroot to JSF to render the components.

       

      Scenario: I select a node on the tree and show the relevant screen on the same page. Then I click on an ajaxCommandButton on the newly rendered screen.

       

      Problem: The click on the button is also calling the click event on the tree. Due to this an IllegalStateException exception is generated as I am trying to retrieve the rowdata in this method.

       

      I have a method expression created and set as the NodeSelectListener on the tree. I do not have a custom nodeslectionlistener.

       

      Could you explain why the tree click event is called out of sequence?

       

      Any help appreciated.

       

      Regards,

      Srikanth

          Hi Srikanth,

           

          ...Then I click on an ajaxCommandButton on the newly rendered screen.

           

          Problem: The click on the button is also calling the click event on the tree

          Is button located inside tree component or outside of it?

            Hi Nick,

             

            The button is outside the tree component. The layout is something like this. There is a main body panel which has the left and the right panels under it. The tree component is in the left panel whereas the screens from the tree actions will be shown in the right panel. The problem is occuring when I click on the buttons present in the right panel. (All panels are rich:panel).

             

            I could actually get away from this situation by changing the state saving method to client in the web.xml.

             

            The problem still occurs if the state saving method is server and that is what we would like to use outside development area.

             

            Another thing that I tried was tree.setAjaxSubmitSelection(false); But this too did not help.

             

            Regards,

            Srikanth

              Ok, I see. Can you please try upgrading to 3.3.3.Final and check?

                Hi Nick,

                 

                Upgrading to 3.3.3.Final did not help. The behaviour is still the same.

                 

                Any other suggestion please.

                 

                Regards,

                      Looks like issue caused by concurrent access to tree. Can you please add a4j:queue to the page and check if this helps?
