If you find yourself needing to insert or paste a large amount of data into a TEXTAREA control, using IBM Rational Functional Tester (RFT), after you paste you might run into an error and experience that the application under test (AUT) is not responding.
The full error message may look like the following:
com.rational.test.ft.UnableToPerformActionException: CRFCN0784E: Application under test (AUT) is not responding while performing the action : setText on control TextGuiTestObject.Try playing back again after restarting AUT.
If the problem persists, avoid performing the above action.
Here is a potential solution to help you overcome this problem:
1. Go to Window > Preferences > Functional Test > Playback > Other Delays
2. Modify the 'Delay before key up' value to '0'.
3. Click on Apply and OK.
