I've a pdf which have to submit a form as html. I've put html submit button to do it with live cycle 8, but i've to load submit url in runtime. I've the url into a hidden field, but i don't know how to load it into the button.
If you are generating the form from an XDP using LiveCycle ES Forms - use the targetURL parameter to specify the HTML target. This can be done at render time of the form (you can render the form at run time based on the user's request by making a call to Forms)
