NLE getChild(int) is null #69

ravijp · 2024-11-25T16:37:12Z

I am trying out the tool on some cobol files and I get following error -

Could you let me know possible reasons for this kind of errors and what kinda resolutions are required?

avishek-sen-gupta · 2024-11-25T17:12:26Z

Please add the following details to help identify the issue.

The smallest COBOL program which can reproduce this issue (remove all code/data which does not contribute to reproducing the issue)
The exact task(s) you are trying to run, together with the command that you issued in the shell.
The stack trace (which you have already provided)
Your platform details (you can paste the output of mvn --version)

@avishek-sen-gupta
it is tough to recreate full COBOL program as it uses copybook files and code is sensitive. I am sharing a gist of the code

I comment the section relevant to PERFORM WRITEQTDQ THRU TDQ-EXIT., I can run the code and generate flowchart.

Error is coming from this section.
I checked the syntex using boradcom package - copybook dependecy etc. everything looks fine.

Let me know your thoughts

avishek-sen-gupta · 2024-11-27T00:19:58Z

Can you paste the command you executed on the command line?

One more thing I noticed in FlowChart, if a Program has multiple EXEC CICS ...END-EXEC. Then in flow chart we get first EXEC CICS code chunk as part of all the EXEC CICS. Showing one example of what I am talking about - > it is the purple box which gets duplicated across all EXEC CICS.

CICS support has not been explicitly added since I haven't had any use cases. If you want to get this fixed, you can open another issue and we can go from there.

This will require adding some specific support for DB2 SQL post-processing. I'll open a specific issue for this and work on it.
