rich:dataGrid empty cell generates invalid XML
-----------------------------------------------
Key: RF-7283
URL: https://jira.jboss.org/jira/browse/RF-7283
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.1
Environment: Jboss 4.2, RedHat 5.2, RF 3.3.1
Reporter: Jeremie Panzer
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://genesis1.spacebel.be/genesis-jsf/portlets/serviceordering/index.jsf?javax.portlet.faces.DirectLink=true
Line Number 105, Column 61: </div></div></td><td class="dr-table-cell
rich-table-cell
"> </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 (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.
