Tony,
When the edit window stays opened then the formedit hidden fields are not being updated by postIt() after submit.
One solution (but not perfect due to the delay) is:
if (!rp_ge.closeAfterEdit) setTimeout(function() { fillData(postdata.id, $t, frmgr); }, 1000);
// at the end of postIt()/ajax/complete function
I have another solution similar to one I posted for the inlinedit.
Let me know if you are interested in that one.
Regards,
Jano
