[richfaces-issues] [JBoss JIRA] Closed: (RF-7283) rich:dataGrid empty cell generates invalid XML

rich:dataGrid empty cell generates invalid XML ----------------------------------------------- Key: RF-7283 URL: https://jira.jboss.org/jira/browse/RF-7283 Project: RichFaces Issue Type: Bug Components: component-tables Affects Versions: 3.3.1 Environment: Jboss 4.2, RedHat 5.2, RF 3.3.1 Reporter: Jeremie Panzer Assignee: Tsikhon Kuprevich Fix For: 3.3.2.CR1 Time Spent: 6 hours Remaining Estimate: 0 minutes I'm using a4j:include navigation and the navigation is working fine as long as I'm not trying to access a page containing a rich:dataGrid component. The starting page is the one containing the dataGrid and is shown correctly. I have a commandLink pointing to another page, and a back button on that second page. When using the back button, thus retrieving the dataGrid page through Ajax, I'm getting the following error: error[9:04:56,090]: Error parsing XML error[9:04:56,091]: Parse Error: XML Parsing Error: undefined entity Location: http://xxx/index.jsf Line Number 105, Column 61: </div></div></td><td class="dr-table-cell rich-table-cell ">&nbsp;</td></tr></tbody></table></div></div></td></tr></table></td><td id="__serviceordering_WAR_genesisjsf_INSTANCE_g8sA_:_viewRoot:j_id9:j_id10:j_id190" style="display: none;;height:100%"><table border="0" cellpadding="10" cellspacing="0" class="dr-tbpnl-cntnt-pstn rich-tabpanel-content-position" width="100%"><tr><td class="dr-tbpnl-cntnt rich-tabpanel-content " style="; "><div class="dr-tree rich-tree " id="__serviceordering_WAR_genesisjsf_INSTANCE_g8sA_:_viewRoot:j_id9:j_id10:me ------------------------------------------------------------^ It looks like the &nbsp; (which is inserted inside an empty cell) is causing this, because if the size of the collection used to populate the dataGrid is a multiple of the dataGrid number of columns, everything is working fine. Here's how to reproduce: index.xhtml <a4j:form> <a4j:include viewId="page1.xhtml" /> </a4j:form> page1.xhtml <a4j:commandLink action="#{myBean.toSecondPage}" value="Go" immediate="true" /> page2.xhtml <rich:dataGrid value="#{myBean.elements}" var="element" columns="3"> <rich:panel><h:outputText value="#{element.id}" /></rich:panel> </rich:dataGrid> and having the myBean.elements collection having less than 3 elements.
