New subject: troubleshooting errors in guvnor
I am attempting to build some rules with guvnor (5.0 latest snapshot),
and I get:
"Sorry, a technical error occurred. Please contact a system
administrator."
I go to the event log and see a:
org.drools.RuntimeException: java.lang.IllegalArgumentException:
argument type mismatch
I have a question:
How can I get the stack trace of the exception, at some point in time
they were available in the app server error log, but I don't see them
there anymore. Stack trace would be of great help to figure out what is
going wrong.
Thanks

Ok, will see if I can add the stack trace back in - did you work out
what the specific problem was ?

OK I added in some stack trace printing.
Note that it really *should* only be bugs that cause that sort of
error - if there is something that shouldn't cause it to happen then
please do raise a JIRA with details, so we can tighten the error
trapping and reporting (so we know if it is a real bug or someting we
need to report more clearly that can be rectified by the user -
without a stack trace being necessary of course !).
Thanks,
Michael.

Subject: Re: [rules-dev] troubleshooting errors in guvnor
OK I added in some stack trace printing.
Note that it really *should* only be bugs that cause that sort of
error - if there is something that shouldn't cause it to happen then
please do raise a JIRA with details, so we can tighten the error
trapping and reporting (so we know if it is a real bug or someting we
need to report more clearly that can be rectified by the user -
without a stack trace being necessary of course !).
Thanks,
Michael.

New subject: troubleshooting errors in guvnor
OK - so that looks like a bug in the declared facts - so that is a
bug, a real bug - so thanks for that JIRA.
As a meta- issue, how can we best report that if, God forbid, an error
happens in that core library (like this) from the guvnor side - is
that stack trace ok? (I think it is to log a bug report) - or is there
some other way we can report it? (if so, a seperate JIRA would be nice
in the GUVNOR project).

Subject: Re: [rules-dev] troubleshooting errors in guvnor
OK I added in some stack trace printing.
Note that it really *should* only be bugs that cause that sort of
error - if there is something that shouldn't cause it to happen then
please do raise a JIRA with details, so we can tighten the error
trapping and reporting (so we know if it is a real bug or someting we
need to report more clearly that can be rectified by the user -
without a stack trace being necessary of course !).
Thanks,
Michael.
