I did however have a few more questions regarding forms.  It looks like form validation is possible with PDF’s.  For example I have a date field and I want the user to input a date in a very specific format. Or an email field that I want users to fill out appropriately.  I am wondering if ReportLab form fields have been configured to support JS validations or regex or anything like this.  I am guessing the answer is no,  but thought I might ask here.

Hi Mike,

at present I chickened out of allowing javascript in reportlab. As you say it is possible, but at present we don't 
support it.
