Rally WSAPI query parameters for start and pagesize ignored when querying the AllowedValues endpoint.
When querying the Allowed Values endpoint to retrieve values for a dropdown field, it appears that both pagesize and start query parameters are being ignored. The response header reflects the values that were provided for both start and pagesize. However, the response seems to always start at element #1 and return all items.
This particular endpoint is a little different because of some backend coding.
To get the call for this endpoint to honor start, pagesize, and other query information, please construct your query like this:
