> This bug affects Form.findSubmittingButton().
> Inside it all the form submitting children of the page are visited. A check is made whether the current form submitting component is a child of the current form. 
> If so another check is performed:
> 	if ((!parameters.getParameterValue(name).isNull()) ||
> 		!parameters.getParameterValue(name + ".x").isNull())
> I saw that in case of a button the condition !parameters.getParameterValue(name).isNull()) is true (returns the "value" attribute of the button), so the button can be considered the submitting component of the form.
> However if there are multiple buttons in the form in this case the first visited button will be returned, which is not necessary the one that actually submitted the form.
