I call listDocuments.do and the resulting jsp-page lists some "channels" where it is possible to delete a chosen channel, by following a link to http://localhost:8080/saveChannel.do?method=delete&id=40278. ChannelAction extends DispatchAction. Now, in ChannelAction, I do a check if the channel can be deleted. If not, I do the following:
The thing is now, that listChannels.do does not seem to be able to display the errors. The attribute is gone from the request. Why is this? I have only done one request, as far as I can see. Does Struts consider going to another Action to be a completely new request?
Request is valid only for request time. If you want have data longer use another scope - session for example. I'm not sure how struts handle with request, but it is possible that after forward it creates new request.
