<![CDATA[Latest posts for the topic "Menuitem throwing NullPointerException"]]> http://jforum.icesoft.org/JForum/posts/list/22.page JForum - http://www.jforum.net Menuitem throwing NullPointerException Code:
               <ice:menuBar id="menuBar">
                  <ice:menuItem id="menuCadastro" value="Cadastro">
                           <ice:menuItem value="Bairro" id="menuIPTUCadastroBairro" link="/tributos/BairroList.seam">
                               <s:conversationPropagation type="none"/>
                     </ice:menuItem>
                  </ice:menuItem>
               </ice:menuBar>
This code is in the menu.xhtml of the generated project using seam-gen set for icefaces and jpa in a war, and is included in the standard template for every page. The menu works perfectly from any page, as do GET calls (mostly s:button and s:link). The problem is when a POST (usually a partial submit) is executed. The following exception is thrown:
10:55:27,250 ERROR [lifecycle] JSF1054: (Phase ID: APPLY_REQUEST_VALUES 2, View ID: /BairroEdit.xhtml) Exception thrown during phase execution: javax.faces.even

This behavior happens both in long running conversations as in short lived ones, and I just can't figure out what's happening. I've tried changing the conversation settings, including nested and named, but to no avail. I'd like to point again that this happens when the menu is NOT accessed. It's just a plain POST from a partial submit or a ice:commandButton click. GETs and direct clicks on the menu work just fine. Any help is very appreciated.
