Subject RE: redirect html:errors to popup window

A slightly different way that we've tried here (I've been scrapping with a
similar issue for a few days now) was to set a 'Window-target' inside the
header on the HttpResponse object when you're within your action class.

Add the following code to your Action class once you've figured out that you
do have some action errors to display

httpResponse.setAttribute("Window-target", "name_of_a_frame");

Under Netscape this causes the page identified by your struts-config file to
be loaded in the target window/frame you've specified. Probably not quite as
flexible as Sean's suggestion but it does seem to work. Unfortunately, it
doesn't work for IE5 (as the Window-target meta tag seems to be Netscape

More depressing for me is that it doesn't work within Mozilla either, and
that's what my client back to the drawing board.....

Subject: Re: redirect html:errors to popup window

redirect html:errors to popup windowThe only way I think you could do this
is via JavaScript ... you could use this tag set:

<logic:messagesPresent >... </logic:messagesPresent>

to determine if there are errors, if so open a popup window, save the handle
... and then within this tag:

<html:messages id="error">...</html:messages>

append to that window the error messages. The JavaScript isn't that hard but
that is honestly the only way I think you could do it. It would look
something like this:

<logic:messagesPresent >
var newWindow = open window here with the size and controls you want
<html:messages id="error">
append to the window the contents of '<bean:write name="error"

Anyone have any other ideas.

Any suggestions on how to redirect <html:errors/> output to a popup window
rather than the page that the form is located on?
Thanks, Jim Canter
