Actually...is this a typing problem?

Calling GetProjectAttributes(66) correctly returns a result of type ProjectVersionAttributeEN[]

However, calling it with GetProjectAttributes(projectid), which is an Int32 and I've checked that it's value is '66' through DiagnosticsManager, throws the above exception.

Disregard that. The exception is coming from GetProjectVersionAttributeValue(version.ProjectID, version.VersionID, attribute.AttributeID).

It still occurs when I enter the int values (verified as correct in the above) manually:

GetProjectVersionAttributeValue(66,196,1);

Please make sure that the version has an attribute value (not default).

The version I'm trying to get the value for already has a (non-default) value.

Just tested and all seems to work. Please catch the Exception (catch (GeminiRestException ex)) and investigate the error details using the debugger.

Ok, I've caught it and am looking through the detail of the exception.

The error's "inner message":

"Project Id does not match saved data Id value: 66."

with inner source "CounterSoft.Gemini.Presenter"
source "mscorlib"
Type HttpStatusCode.InternalServerError

There seems to be a 500 server error somewhere. The path of the response uri is

"/api/projects.ashx/projects/66/versions/196/versionattributevalues/1

And the headers read:

Connection: close
Content-length: 1826
Cache-control: private
Content-type: text/xml
Date: is correct (copying manually)
Server: Microsoft-IIS/6.0
X-AspNet-Version: 2.0.50727
X-Powered-By: ASP.NET

But I'm not seeing any more information I can use to try and solve it.

Any hints on where to look? Or is that enough?

The error suggests that the attribute value does not belong to the project sent in (66).

Are you sure that the attribute value id is correct and has a value?

Yeah.

http://bilby/project/Admin/Versions.aspx?PROJID=66

has:

and version attributes for 0.7 are:

"test release notes", where the default value is "Release notes"

Line from SQL database:

5 1 66 196 test release notes<br />
<Binary data>(attributevalueid,attributeid,projectid,versionid,attributevalue,tstamp)

I've got it!

The final argument of GetProjectVersionAttributeValue - "attributeid" - is not the attribute id as it is referred to in the attribute table. It is referring to the attributevalueid from the attributevalues table.

This means you need to know the exact entry in that table when trying to retrieve a version attribute value - surely not the way it's supposed to work?

I'd have thought the entity returned should be that entity that matches the 3 arguments, as in the following:

My database table entry:

5 1 66 196 "test release notes<br />"
"<Binary data>"(attributevalueid,attributeid,projectid,versionid,attributevalue,tstamp)

So at the moment to access this elemt from the API, I need to call GetProjectVersionAttributeValue(66,196,5). Surely it's better to access it using GetProjectVersionAttributeValue(66,196,1), since '1' is the attribute for all versions of this project - not just those with an already-defined value?

EDIT:

I've also found a workaround. Using GetProjectAttributeValues(projID,versID), you can obtain an entity that contains the attribute AttributeValueID - exactly the number required above. It requires a bit of looping and searching, but it does the job.

Done. Thanks for your help.
