Hi Mayank,
For your answer to 1. This is not the behavior I am seeing when xdp is rendered as HTML in workspace. The complete button has no link to any buttons on the form and all it can be used for is to submit. It does validations if xfa.host.validationsEnabled is set to true, but other than that, it executes no button in the form. If you want I can show this to you in a meeting session and you can clarify what you are saying. Also, the link that you have provided applies to when you are submitting the form as PDF, not when the form is XDP rendered as HTML. Which takes me back to my original question, how can I invoke the complete button in workspace from my form when I it is an xdp rendered as html.
For 2. I'll check out the link you provided and see if I can follow the directions. Thanks.
