Description of problem:

I have a process definition with 2 process variables, var1 and var2. I start few process instances with different values for var1 and var2 and when I want to query one particular process instance with var1=value1 and var2=value2 I do the following request:

http://localhost:8080/business-central/rest/query/runtime/process?processinstancestatus=1&var_var1=value1&var_var2=value2&

However, I get no results from this request:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><query-process-instance-result/>

I will add a comment linking to the reproducer.

Requesting blocker since this issue needs to be fixed in regard to BPMSPL-84.
