CA Plex C++ application runtime crash in OB721NWI.dll during text field navigation

Products

• CA Plex

Issue/Introduction

Our Plex C++ app crashes every time users use the mouse or arrow keys to navigate to a text field. The text field is an ActiveX control field.

The Windows event view displays

Faulting module name: ob721nwi.dll, version: 7.2.24.0, time stamp: 0x57b1b317
Exception code: 0xc0000005
Fault offset: 0x00024e11
Faulting process id: 16f8
Faulting application start time: 01dcc10252730cdc

The crash does not occur if users simply type over the existing text.

Environment

CA Plex versions 7.2.1 and 7.3.0

Resolution

Please modify the app ini file to change the SingleLineEdit value to 0

[NativeControls]
SingleLineEdit=0

If this change does not fix the issue please contact Broadcom Support. 

Additional Information

With the SingleLineEdit=0 setting the control basically is turned to underlying operation system which ensures proper behavior for accessibility.  This setting is sort of a legacy one and we recommend to set it to zero(0) for OS compatibility.
