Item823: FormPlugin thinks beforeclick text is valid entry

beforeclick text is removed when clicking in the field, then the field is empty. Still the validation code thinks the field contains information, so no error goes off when submitting.

Test code:

%STARTFORM{
name="dropdownform"
action="view"
topic="%WEB%.%TOPIC%"
method="POST"
validate="on"
}%
%FORMELEMENT{
type="text"
name="To"
beforeclick="Who is going to read this"
mandatory="on"
}%
%FORMELEMENT{
type="text"
name="Subject"
beforeclick="What is it about"
mandatory="on"
}%
%FORMELEMENT{
type="submit"
buttonlabel="Submit"
}%
%ENDFORM%

This is a fix using javascript:

for(var i=0; i<document.dropdownform.elements.length; i++)
{
   if (foswiki.CSS.hasClass(document.dropdownform.elements[i], 'foswikiInputFieldBeforeFocus')) {
      document.dropdownform.elements[i].value = '';
   }
}

but the solution should be done in FormPlugin code:

• if has field beforeclick, check if value is the beforeclick value, if so, clear value

Fixed in FormPlugin 2.0.
