Void archetype accessing CKM web service (and website?)

Accessing CKM via web service I have found that the archetype
openEHR-EHR-OBSERVATION.intravascular_pressure-cvp.v1 returns an empty
archetype (0kb size)
http://openehr.org/ckm/services/ArchetypeFinderBean/getArchetypeInADL?archetypeId=openEHR-EHR-OBSERVATION.intravascular_pressure-cvp.v1

Related archetypes
openEHR-EHR-OBSERVATION.intravascular_pressure-jvp.v1 and
openEHR-EHR-OBSERVATION.intravascular_pressure.v1

If you visit this archetype on CKM seems ok at first, but for some
reason archetype definition is all grayed out

Hi Diego,

Confirmed as a bug.

There seems to be a problem with an index on the archetype id and for some obscure reason doesn’t find the archetype -cvp archetype, but finds the -jvp one without problems.
If I remove this index, it works ok. While we investigate the underlying issue, I have therefore temporarily removed the index, although it (slightly) impacts on performance elsewhere.
In any case, you should now be able to access the url ok.

BTW, greyed out parts in the archetype views indicate that the part has not been specialised.
There is nothing much in this archetype that has been specialised as far as I can tell except for the concept name - this is why everything in the definition is greyed out.

Regards
Sebastian
