Do something based on existence of action error - How?

[james billa]

Hi ,

I am using Struts 2.1.6. I want to show the content  a <tr> only if action
error exists. If not I don't want to show the content of my <tr>. How do I
check whether action error exists or not in my page? The action error is set
by my action class if there is an error.

I have done to coding (CSS) to show or hide the <tr>. But not sure how to
implement it by checking the action error. Thanks.

Thanks
