I do agree AJAX request is best approach, and that is how I am doing it in numerous other locations. I just needed a fix for this one instance as it would have been a lot more work to refactor the modal to use AJAX for the select list, then it was to implement the refresh of the initial modal when the secondary modal executed a save.
I was able to resolve this using the existing
_resetUserSpecificPermissions()
in _PermissionsModal.js
as an example, tweaking it to my specific need!
Just asking - I rubber duckied my way to the solution :)
ModalManager - getModalId() and jQuery to modify the css.
$thisModal = $('#' + _modalManager.getModalId()).find(".modal-content").css({ "width": "900px", "margin-left": "-10px" });
Hmmm, in my continued reading it appears Settings Manager uses Cache, maybe extending OU to have settings is the correct route.
<cite>hikalkan: </cite> One reason can be customErrors should be "On" in for web.config file.
That was the culprit, thank you sir.
