gustavofarias Posted July 26, 2013 Share Posted July 26, 2013 The ultimate guide only says:Pattern. Similar to a format mask: the user’s entry must match it.Is this really a field for a mask or should it be a regular expression? I tryed to use the regex dd for a text datatype, and it almost worked. I say almost because the empty string is not being rejected. Link to comment Share on other sites More sharing options...
