Stacktrace in IVCT GUI #213

Closed bergtwvd closed 4 years ago

bergtwvd commented 5 years ago

When I start the VTMaK composition under https://github.com/IVCTool/IVCT_Compositions/tree/master/ivct-vtmak I cannot change the connection string to (setqb RTI_tcpPort 4000) (setqb RTI_tcpForwarderAddr \"localhost\") for the SUT vrf. The value remains unchanged after save. When I look in the console I see the following stacktrace:

The problem seems to be that the call dir.listFiles(); returns a null pointer because the dir object did not point to a valid directory name. The null pointer is used without being tested causing the null pointer exception. The directory is determined by the value of IVCT_TS_HOME_ID + tsLibTimeFolder from the badge. The IVCT_TS_HOME_ID either contains a wrong value or it is overwritten due to the changes in SUT common parameter logic.
