Martin,
That is correct, the stuts error tag cannot actually invoke a JavaScript
method, however it can write one out to the screen and have the browser
throw such an error at run time of the page. I will be posting a follow up
thread to explain what throwError() (the JavaScript form my response) might
do with a sample set of code. Without violating any code ownership issues
for the specific implimentation developed for the site listed below, the
general concept and a sample modified implimentation will be available in a
new thread I am going to post in a few hours. Please see the "JavaScript
with html:errors - new STRUTS validation" thread coming up very soon, I am
just putting the finishing touches on the files.
Thanks,
Adam S. Grohs
