Re: [Webwork-devel] action chaining

[Patrick L. <pli...@ho...>]

Matt,
This doesn't appear to be working for cases such as the follow (which I used
extensively before action chaining, and i thought it would still work now
too, but maybe not):

Details.action=paws.Details
Details.success=details.jsp

EditMetadata.action=paws.metadata.EditMetadata
EditMetadata.error=edit.jsp
EditMetadata.success=Details.action

EditMetadata and Details both extends AbstractPAWSAction, which looks like
this (get/set for the following):

id
title
language
creator
...etc

EditMetadata and Details both don't have any extra properties worth
mentioning in this example. Now EditMetadata.doExecute() is called and
returns SUCCESS, but then the browser gets a blank page at
http://localhost/paws/csh/EditMetadata.action and the console shows this
error:

java.lang.IllegalArgumentException: No error view found for action Details
        at
webwork.dispatcher.ConfigurationViewMapping.getView(ConfigurationViewMapping

        at
webwork.dispatcher.ServletDispatcher.getView(ServletDispatcher.java:336)
        at
webwork.dispatcher.ServletDispatcher.service(ServletDispatcher.java:258)

I added "Details.error=details.jsp" and instead of getting the error, I got
returned to details.jsp just fine, except that all the properties were null
so errors were all over the place. Any idea what's going on here?
