'ClickCell' method has stopped working with error: "An error occurred"

Hi,

I need to select cells on a table widget of our desktop app. I have been able to successfully do this using the ClickCell method and this was working perfectly ok for a while (more than a year). However in last couple of weeks, this method has started failing with an error "An error occurred".

I also recorded a script by performing the steps manually. Then I ran this recorded script (attached below). This script also fails with the same error. I do not see the issue when I click the cells manually. The issue is only when running a script.

Recorded script:

function Test12()
{
var tableWidget;
tableWidget = Aliases.....tableWidgetProjects;
tableWidget.ClickCell("1", "Name");
tableWidget.ClickCell("2", "Name");
}

Under 'Additional Info':

Possible reasons:
1. The application stopped responding.
2. The application was compiled incorrectly (see the Open Applications topic in the help system).
3. An error occurred in TestComplete/TestExecute.

Technical information:
37 0x8002802b (Element not found.) .

Tested object:
Aliases.......QtObject("tableWidgetProjects"))

Any help is appreciated. Thanks!
