Forget about having validation called automagically then you don't have to worry about any of the hoops.

Re: html:cancel usage
Hi,
Just for the record, I have contrived a particularly nasty work-around for
this problem and share it in case anyone ever ends up as desperate as me!
To recap, I have 3 buttons on a form including a cancel button for which
there should be no validation.
Because I have implemented a LookupDispatchAction class to handle these
buttons, I cannot just use the tag 'as is' because I get the
following exception (my method param is called 'method'):
javax.servlet.ServletException: Request[/createContact] does not contain
handler parameter named method
If you include property="method" with the tag, you lose the
exception but validation still takes place.
So what I have done (if you will excuse the fish-heads) is:
Use a standard html hidden tag (the struts tag moans about not
having getter for the property x) with a dummy name:
Have your cancel button call some JavaScript:
and the JavaScript is:
function sendCancel()
{
document.forms[0].elements[0].name="org.apache.struts.taglib.html.CANCEL"
return true;
}
I have tried all the other suggestions in every combination but can't get
anything more elegant to work. This works but I'm not looking forward to
the code review!
Regards,
Andy

It says the following about the html:cancel 'property' attribute in the Html Tag Developer Guide: "WARNING - If you set this attribute to a value other than the default, this will NOT be recognized as the cancel key by the Struts controller servlet or the Action.isCancelled() method. You will need to do your own cancel detection". But nearly always a developer will be overriding this property with a value so that they can distinguish which button was clicked by the user to satisfy the Dispatch Action class. (I say this as I assume there will often be a submit button as well that should invoke validation). Why would a developer be overriding the property value for html:cancel? It makes sense to do it for html:submit tags to be able to detect which submit button was clicked when the execute() method of your action class is called. I just set all of the html:submit tags to use the same property name, such as "MyAction", and then I retrieve that from the HTTP request that is passed in to execute(). First, however, I test the return value of isCancelled() to see if html:cancel was clicked, and if it is false, then I test value of "MyAction" to find out which html:submit button was clicked. If you don't override the property value for html:cancel, you are observing that the Struts Validator plug-in still tries to validate the fields on the submitted form?

Re: html:cancel usage
What I usually do is check for isCancelled() in my Action (or BaseAction) before anything else so I can forward to the appropriate place if cancel was clicked. As for the validation, I had to put my validation in a private method in the Action instead of using the one in the ActionForm.

RE: html:cancel usage
Hi, Has anyone else had a problem with this? I am using Struts 1.1 but presume it has worked in this and previous versions as it must come up in almost every project. I cannot switch validation to false as my submit button does require validation. I suppose I could put the cancel and submit buttons inside seperate form tags but this seems a little contrived.

Re: html:cancel usage
I believe the validation still happens because the validation step occurs before the appropriate method in the action class in determined. I got around this by turning off automatic validation.

RE: html:cancel usage
Which version of Struts are you using? Are you using Struts 1.1 or 1.2.x? The cancel functionality is supported in Struts 1.2.x. I use this functionality and works fine for me. I was using the MappingDispatchAction.
