stacktrace

REST client throws NPE when is trying to retrieve List<VariableInstanceLog> of all variables for given process instance id. Take a look at the attached stacktrace.


Steps to Reproduce:
1. start business-central
2. create some process definition with a process variable
3. start the process
4. query for the history of all variables (and your process instance id) via clie

Additional info:
http://localhost:8080/business-central/rest/history/instance/${2}/variable/
returns:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><log-instance-list/>

but
http://localhost:8080/business-central/rest/history/instance/${id}/variable/${variable_name}
returns valid information about the variable.

Radovan, could you retest this with ER2? This looks like a duplicate of BZ-1070211.

Comment 2 Marco Rietveld 2014-03-03 11:48:53 UTC 
Part of this problem is actually a duplicate, part is isn't: the NPE is unique to this bug.
