Re: how to check if html:errors will display anything

[Riyad Kalla]

Great question, I solved this by checking if Globals.ERROR_KEY was null 
or not, but I still wanted something more, because I set aside a small 
margin in the top of my page for global errors, like System errors... 
and I only wanted to display the margin IF there were some 
ActionMessages.GLOBAL_MESSAGE messages in the ActionMessages object, but 
I didn't find a quick way to check this.

However if you just want to check for any errors at all, this should do 
the trick:
<logic:notEmpty name="<%= Globals.ERROR_KEY %>">
</logic:notEmpty>

How can I check if the html:errors tag will display anything down inside my
jsp page? I have the html:errors tag inside a table tag and I don't want the
table generated at all if there aren't any errors to display.

Thanks,
