Another Web Service Question

 

{"The specified type was not recognized: name='ParentOf', namespace='http://ideablade.com/PersistenceWebService/Types/', at <ChildOf xmlns='http://ideablade.com/PersistenceWebService/Types/'>."}

 

The Entity Organization is a Web Method the Relation Property is WebServiceVisable.

 

If the span returns no values it passes. If the the span has values it throws the error.

 

Code: (Notice I am not reference ChildOf as it does in the error)

Query aQuery = new Query();

QueryClause aClause = new QueryClause();

aClause.ColumnName = "Name";

aClause.ColumnValue = "Oregon Cities";

aClause.Operator = QueryOp.EQ;

 

QuerySpan mOrgOrgGroupSpan = new QuerySpan();

mOrgOrgGroupSpan.Relations = new string[] { "ParentOf" };

 

aQuery.Spans = new QuerySpan[] { mOrgOrgGroupSpan };

 

aQuery.Expressions = new QueryExpression[] { aClause };

 

Organization[] mOrgs = mWebService.GetOrganizations(aQuery, String.Empty);

 

If it's still not making sense, please send your .ORM file and the generated webservice class to support.

So, you've got -

 

Organization entity:

  - ParentOf  - returning a list of OrganizationGroups

  - ChildOf - returning a list of OrganizationGroups

  - ... other props

 

OrganizationGroup entity:

  - ParentOf - returning an Organization

  - ChildOf - returning an Organization

  - ... other props

 

When you call GetOrganizations with no spans in the query this will work and return only the requested organization(s).  Adding spans for either the ParentOf or ChildOf properties fails because the XML generator is confusing the various ParentOf/ChildOf properties with their entity types.  A workaround would be to retrieve organizations and organization groups in separate queries. 

 

We'll have this fixed in the next release (due in early May).
