DateTime control issue in modal window

Not Applicable

Steps to Reproduce

1. Create a section containing a button. 
2. On click of button, have a local action to open in modal dialog.
3. The modal dialog should have a DateTime Control.
4. Save the flow and run the use case.
5. Open the flow and scroll the page.

Root Cause

The popup used by Datetime is always added to the form element inside harness div and if the harness scrolls the popup also scrolls with it. 


Add the below code in the UserWorkForm which should be called when the body loads:

(function (p) {
/* ....
.... */
    if( pega.u.d.bModalDialogOpen && pega.u.d.modalDialog && pega.u.d.modalDialog.body){    
        p.util.Event.addListener($(pega.u.d.modalDialog.body).find(".modal-scroll-panel").get(0), 'scroll', scrollHandler);    
/* ....
.... */


1. The issue reported, that is, the popup scrolls along the screen, is fixed in Pega 7.1.10. Similar solution was provided as a local-change in Pega 7.1.5.
2. Another issue is with the transition, where the popup does not scroll smoothly and it also comes on top of the header. This issue does not replicate in
Pega 7.1.10 with other browsers except IE. This is scheduled to be fixed in Pega 7.1.11 for IE browser.
