Hello,
I am using openehr 1.0.4 (1.0.11-SNAPSHOT as well) java ref impl libs to process a oet template.
I get the error,

org.openehr.am.template.FlatteningException: no constraint on path: /items[at0046] of openEHR-EHR-CLUSTER.symptom.v1
at org.openehr.am.template.Flattener.applyRule(Flattener.java:802)
at org.openehr.am.template.Flattener.applyRules(Flattener.java:779)

the same thing happens with both versions, 1.0.4 as well as 1.0.11-SNAPSHOT.
Link to the oet file I am trying to process.
https://drive.google.com/file/d/0B2rfmXR_HvZQanQ0eVFFRDdNTUE/view?usp=sharing

The java code is out of the test case for OET (oet-parse module in openehr, javalibs maven project).
I am working on Linux, Jdk1.8, maven3 dev-environment.

Please help, What am I missing? What do I have to do in the template to make this work?
Is the template file itself invalid?
Please help with this i am stuck and unable to proceed.

Thanks,
Subhro.
