cancelButton using WAButtonTag

Hi!! I'm developping an application using JQuery decorations, where the
buttons have icons.

I have one button inside a form that's suposed to execute a Task, but I wish
NOT to submit the form by pressing that button given that I do a series of
validations on every input callback. So if the form submits, it fails
because of the validations. I've tried using a #cancelButton but
unfortunately it generates a <input type="button" ...> which doesn't support
JQuery's .button icon styling (which I need in order to keep the layout of
the page)

Is there any way to achieve the same behaviour of cancelButton by using an
ordinary button?

I've tried using a #button bePush; and invoking a callback via ajax, but
that ajax callback doesn't execute the button's callback, where I'm making a
#call: to a WATask. Here's a piece of code for that purpose:

       aCanvas button
               bePush;
               callback: [ self call: MyTask new ];
               script: (aCanvas jQuery this button primaryIcon: 'ui-icon-plus');
               onClick: "I think here I should execute the button's callback"
               with: 'Execute Task'.

Any ideas on how to do this?

Many thanks in advance!!
Alejandro

You can just put the ajax callback in the click handler.

Hi, John! Thanks for your quick reply!

Unfortunatelly it doesn't work. Here is my code:

aCanvas button

  bePush;
  callback: self callback;
  script: (aCanvas jQuery this button primaryIcon: 'ui-icon-plus');
  onClick: (aCanvas jQuery ajax serializeThis);
  with: self label.

Is there any other way to disable callbacks execution when a form submits? I've also tried emulating cancelButtons behaviour by wrapping my own callback with WACancelActionCallback it complains about needing a NiladicValuable block.

Thanks again!
