Trouble Accessing Attribute Values of an Attribute Profile
Answer

Hi

I have started working with Attribute Profiles. I created a simple attribute profile class hierarchy using two classes where both have one attribute (besies the typical AttrRep, ClassAbstract etc.). I then created an instance in the modelling toolkit, set the value of the one attribute and tried to retrieve it using the following AdoScript:
1CC "Core" GET_ALL_ATTRPROF_SUBDIRS
2# Since right now there is only one instance this shouldn't be a problem
3CC "Core" GET_ALL_ATTRPROF_THREADS_IN_DIR apdirid:(VAL token(apdirids,0," "))
4SETL thingid:(VAL apthreadids)
5CC "Core" debug GET_ATTRPROF_CLASS_OF_THREAD apthreadid:(thingid)
6# Again since there is only one possible attribute this also shouldn't be a problem
7CC "Core" debug GET_ALL_ATTRS classid:(apclassid)
8CC "Core" debug GET_ATTR_VAL objid:(thingid) attrid:(VAL attrids)

Everything works with the exception of the last GET_ATTR_VAL call. This one returns an ecode:71 with errtext:"ATTRIBUTEOWNER_NOT_EXISTING". Could it have to do something with the class hierarchy? Or are the attribue values of Attribute Profiles accessed differently?

Similar as for model versioning you just have to get the version id from the thread → those are then the actual instances. Thus, you need one additional line:

 1
 2CC "Core" debug GET_ALL_ATTRPROF_SUBDIRS
 3CC "Core" debug GET_ALL_ATTRPROF_THREADS_IN_DIR apdirid:(VAL token(apdirids,0," "))
 4SET nApThreadIDs:(apthreadids)
 5
 6CC "Core" debug GET_ALL_ATTRPROF_VERSIONS_OF_THREAD apthreadid:(VAL token(nApThreadIDs,0," "))
 7SETL nApVersionIDs:(VAL apversionids)
 8
 9#This is a bit short-handed, assumes only one thread returned.
10CC "Core" debug GET_ATTRPROF_CLASS_OF_THREAD apthreadid:(VAL nApThreadIDs)
11CC "Core" debug GET_ALL_ATTRS classid:(apclassid)
12CC "Core" debug GET_CLASS_NAME classid:(apclassid)
13
14CC "Core" debug GET_ATTR_VAL objid:(nApVersionIDs) attrid:(VAL attrids)

Alternatively, you can use the AQL queries, instead of working with directories, to handle the instances directly.

Thank you, it works now using the CC "Core" debug GET_ALL_ATTRPROF_VERSIONS_OF_THREAD ... you described.
Using AQL to access the Attribute Profiles also sounds interesting. How can I do that in AdoScript? How would the CC "AQL" EVAL_AQL_EXPRESSION ... look to access an Attribute Profile instance that is not assigned to any model/object attribute?
