Extended DataTable issue?
Hi All,
I have an extended data table with parametrised rendering for each column something like this :
<rich:column rendered="#{reconSettings.param}">
<f:facet name="header">
<h:outputText value="Col1" />
<a4j:commandLink action="#{reconSettings.removeColumns}" render="table">
<a4j:param value="5" assignTo="#{reconSettings.columnId}" />
</a4j:commandLink>
</f:facet>
<h:outputText value="#{reconItem.value}" />
</rich:column>
When i move this colum everyting is ok but when after i click on the command link i have this exception :
