Delete action does not work in repeating dynamic layout



The Delete action does not work for a repeating dynamic layout when sourced by a page group property.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Configure a repeating dynamic layout with a page group property
  2. Configure a Delete action event
  3. Attempt to delete a record

Root Cause

Delete action does not support page group sourced repeating dynamic layouts.


Perform the following local-change:
  1. Include the following JavaScript function in a JS file included in the Harness or in the UserWorkForm:

    function removeFromPageGroup(event) {
        var pageGroupProperty = jQuery('[data-repeat-source]').attr('data-repeat-source');
        var rowBaseRef = pega.u.d.getBaseRef(;
        var lastLeftParentheses = rowBaseRef.lastIndexOf("(");
        var lastRightParentheses = rowBaseRef.lastIndexOf(")");
        var subscript = rowBaseRef.substring(lastLeftParentheses + 1, lastRightParentheses);

        var safeUrl = SafeURL_createFromURL(pega.u.d.url);
        safeUrl.put("pyActivity", "@baseclass.RemoveFromPageGroup");
        safeUrl.put("PageGroupProperty", pageGroupProperty);
        safeUrl.put("Subscript", subscript);

        pega.u.d.asyncRequest("GET", safeUrl, {
            'success': function() {
                var sectionNode = pega.u.d.getEnclosingSection(jQuery('[data-repeat-source]').get(0));

  2. Change the action from 'Delete item' to 'Run script'
  3. Set the function name as 'removeFromPageGroup' and add a parameter with value, 'script:event'
