Save checkbox parameter in a RunBaseBatch

Hi, I'm created a form that is being called by a class extending from RunBaseBatch with two parameters, one Description type and another one which is NoYesId, when I create the batch and look at the parameters, the checkbox value is not saved, this is what I have:

In the form, an edit method that calls the parmMethod in the class:

edit NoYesId editNoYesId(
boolean _set,
NoYesId _noYesId
)
{
if (_set)
tutorial_RunbaseForm.parmNoYesId(_noYesId);

return tutorial_RunbaseForm.parmNoYesId();
}

Then in the class:

NoYesId parmNoYesId(NoYesId _noYesId = noYesId)
{
;
noYesId = _noYesId;

return noYesId;
}

Am I missing something? thanks!
