smart deployment message

[ismail1]

Hi folks, its getting harder to deploy process when it gets bigger….
Eclipse editor does not complain about xml but when deploying process , usually "xml parse error" is displayed, but no hint about where the problem can occur….
Is there a way that will make life easier about this? can this message set to be more detailed, line number …
How can i fix xml, notepad++ says its good xml, yaogjang bpmn editor says it s good…but cant deploy…

Any eagle eye help?

I think you should use a ":" instead of a ",", when delimiting the choices of the inline-if ('approved':'disapproved. Sorry')

Thanks Frederick,
in my case, logs are printed to server console,  it doesn't include xml parse errors…
here is my console log when deploying, (at screen error message 'xml parse error' is displayed…)
Are those logs you pasted here taken from console log, how can i achieve my console prints xml parse errors too? or are there any log files, should i increase log level to debug for some packages or so?

Since the error is logged, I recon the cause should be logged as well (I don't see the root of the stack pasted below, so perhaps you're missing a part). Log-level doesn't influence the depth of exceptions logged. What about catalina.out and localhost.log?

Related: I have similar problems when using the KIS editor. Sometimes I get exceptions like this:
