I was reviewing the lab submissions templates for non integrated labs 

I was looking at adding tests 

I couldn't work out the correct JRXML to access the 'tests' field 

what I noted was the investigations archetype actually has 2 fields with the same name?

In any event I wanted to add a list of associated tests to a submission using a subreport

I was trying to work out the datasource expression for the subreport but couldn't quite work the XPath out

Then in the subreport display a list of test with codes 

On that note the "Code" field on Lab tests seems to be readonly by default even when creating a new test.  Not sure why - for non integrated labs the field should be editable.
