Stateful session bean serialization error.
Hi,
I have a problem that when one of my stateful session beans is passivated/loaded it throws the following error:
javax.faces.el.EvaluationException: Exception while invoking expression #{loadPassage.load}

*/
@RequestParameter
private String model;
/**

*/
@RequestParameter
private String colour;
/**
* Passage reviewComment.
*/
@RequestParameter
private String comment;
The bean has a mapping in the pages.xml and used by a legacy web app which pass in parameters via a get and expects javascript back.
<pages>
<page view-id="/loadUser/*" action="#{loadUser.load}" />
<page view-id="/loadPassage/*" action="#{loadPassage.load}" />
<page view-id="/loadStatus/*" action="#{loadStatus.load}" />
</pages>Any ideas or is it better to use servlets for this?
