Fomat Validation Issue

Hi,
I’m having some strange problem with the format validation.
I have created a dinamic form in table view.
One of the fields has cuantity data, so I decided to use some field format validation.
This one in particular, ‘#;INVALID’. This allows me to automatically validate negative amounts.
The problem is after fixing one of the validation errors, all the column changes to red characters as in the validation error. :?
I’m uploading some print screens to explain my situation.

Before fix:

After fix:

I’m using Servoy 6.0.4 and Java 1.6.0_29-b11

Thanks for the help.
Cheers

what exactly are you doing/configuring for those fields?
