Property value appeared to be disappearing with Accessibility

SA-2179

Summary


Designers had implemented a grid repeat layout that contained two checkbox and two date fields.
For this they have added the same DateTime property onto the grid twice. Where each DateTime property is only displayed if an adjacent checkbox is checked.
Also the two checkboxes cannot both be ticked, so you would only ever have one of the DateTime entries visible.

However, when testing it was noticed that when they enable Accessibility (PegaWAI) that the DateTime that they set on the second controls disappears when they Submit the form.

 

Root Cause


Examination of a Fiddler trace was showing that the property was being sent twice.
Even when Accessibility was removed from the application the HTTP request information was still showing the property being sent twice, but in this scenario it chose the one with datetime value set.

Resolution


This was deemed to be a potential contention issue with the same property being processed twice.
The problem was rectified by storing the two DateTime values in two different properties.
