[TYPO3-mvc] _hmac behaving strangely

[Braulio J. Solano-Rojas]

Hello.

I have a form that was working, but suddenly, I do not know why it 
stopped filling the _hmac.

Plus now I have fields without a name, like:

<input size="45" type="text" name="" value="" />

It's like there was no object assigned to the form, but it is.

I do not know what could have changed.  Has someone a clue?  Is this a bug?

Best regards,

B.
