Search module bug

Am using ScriptCase Prod: 9.2.016
Everytime I enable search module on grid, I get this error

2 = in_array() expects parameter 2 to be array, string given
C:\Program Files\NetMake\v9\wwwroot\scriptcase\devel\generator
m_gp_pesq.php 1453

This bug has literally stalled my project, please have it rectified.

Is there a solution to this bug, because even updating not helping.
