Jan Ziegler commented on RF-4117:
---------------------------------
I think I found the solution by myself, but first some example code:
Bean:
public class TestBean implements Serializable
{
private HtmlDataTable dataTable = new HtmlDataTable();
public HtmlDataTable getDataTable()
{
return this.dataTable;
}
public void setDataTable(HtmlDataTable dataTable)
{
this.dataTable = dataTable;
}
}
XHTML:
<t:saveState value="#{testBean}" />
<h:dataTable binding="#{testBean.dataTable}" />
<h:form>
<h:commandButton value="doAction" action="someAction"/>
</h:form>
The problem is explained here:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg14990.html
If you use <t:saveState> for caching a bean in the viewRoot it will be
serialized and therefor all of its members. But HtmlDataTable is not
serializable by spec.
The solution is to make the HtmlDataTable in the bean TRANSIENT:
private transient HtmlDataTable dataTable = new HtmlDataTable();
So the problem is not a Richfaces problem I think. It´s just appearing right
now, because State-Saving is "activated" after implementation of RF-4108.
Does this mean, that org.apache.myfaces.SERIALIZE_STATE_IN_SESSION wasn´t
recognized before?
