Nils-Helge Garli commented on WW-1286: -------------------------------------- The patch for WW-1313 will also resolve this issue. > ClassCastException in LocalizedTextUtils in Portlet when doing a submit to a > model driven action > ------------------------------------------------------------------------------------------------ > > Key: WW-1286 > URL: http://issues.apache.org/struts/browse/WW-1286 > Project: Struts Action 2 > Type: Bug > Components: Portlet Integration > Versions: WW 2.2.2 > Reporter: Nils-Helge Garli > Assignee: Rainer Hermanns > Fix For: 2.0.0 > > Problem with ww:text when a ModelDriven action is invoked in the event phase > of a portlet request cycle, and the result is a jsp, causing the > DirectRenderFromEventAction to execute. Root cause is that the > Jsr168Dispatcher pushes the action executed in the event phase on the top of > the stack when executing in the render phase (to preserve form parameters and > possible error/validation messages). > This causes a NPE in the following code in LocalizedTextUtils: > [code] > if (ModelDriven.class.isAssignableFrom(aClass)) { > ActionContext context = ActionContext.getContext(); > // search up model's class hierarchy > ActionInvocation actionInvocation = context.getActionInvocation(); > // ActionInvocation may be null if we're being run from a > Sitemesh filter, so we won't get model texts if this is null > if (actionInvocation != null) { > Object action = actionInvocation.getAction(); > Object model = ((ModelDriven) action).getModel(); > if (model != null) { > msg = findMessage(model.getClass(), aTextName, > indexedTextName, locale, args, null, valueStack); > if (msg != null) { > return msg; > } > } > } > } > [/code] > ww:text evaluates the action on the top of the stack, which is the model > driven action previously pushed onto the stack, but > actionInvocation.getAction() returns the DirectRenderFromEventAction which is > not a model driven action. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/struts/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
