Cannot scroll to see classic harness action area buttons



After upgrading from PRPC 5.5 with fixed portals, it is not possible to scroll down to see the standard Action Area Harness buttons.  Only a piece of the buttons are visible.

Error Messages

Not Applicable

Steps to Reproduce

Use standard 5.5 Perform Harness with Action buttons.

Root Cause

A backwards compatibility defect in Pegasystems’ code or rules .  The computation is now different with dynamic portals.  The Rule-Utility-Function (RUF) 
Harness • pzGenerateHarnessHeaderAndFooter computes the height of the <div> "HARNESS_BUTTONS" in this manner:

aDocument.append("\n\t\t\t<div id='HARNESS_BUTTONS' class='buttonTableBoxStyle' style='height:" + (pyHeight + 27) + "px'>");

The computation for the vertical scroll bar does not provide enough movement to scroll far enough to fully display these buttons.  The computed value is 47px.


Perform the following local-change: Open the button definitions and on the presentation tab, the advanced options, change the height from 20 to 60.  This will increase the vertical height of the button row for 47 to 87 pixels, and the buttons will display properly
