Subject Re[2]: Unable to access "Choices" in DotCMIS 0.7
Date Fri, 27 Nov 2015 21:09:13 GMT
Thank you, Florian!

The problem was that I needed to cast the property definition I was 
looking for to "IPropertyStringDefinition" before I could see the choice 
list.

Here is the corrected, working code (in C# - VB.Net will work exactly 
the same):

        private void getChoiceList(string docClassName, string propName)
         {
             logMsg("Querying TypeDefinition(" + docClassName + ")...");
             ITypeDefinition docClassDef = 
m_session.GetTypeDefinition(docClassName);

             logMsg("Searching for PropertyDefinition(" + propName + 
")...");
             IPropertyDefinition propDef = null;
             foreach (IPropertyDefinition pd in 
docClassDef.PropertyDefinitions)
             {
                 if (pd.Id.Equals(propName))
                 {
                     propDef = pd;
                     break;
                 }
             }

             logMsg("Choices:");
             IPropertyStringDefinition stringPropDef = 
(IPropertyStringDefinition)propDef;
             int i = 0;
             foreach (IChoice<string> ch in stringPropDef.Choices)
             {
                 logMsg("  ch[" + i + "]: " + ch.DisplayName + "=" + 
ch.Value);
                 i++;
             }
         }

     - Output =>
11/27/15 13:00:09 Querying TypeDefinition(RGBClass2)...
11/27/15 13:00:09 Searching for PropertyDefinition(RGBChoiceList)...
11/27/15 13:00:10 Choices:
11/27/15 13:00:10   ch[0]: 
Joe=System.Collections.Generic.List`1[System.String]
11/27/15 13:00:10   ch[1]: 
Dan=System.Collections.Generic.List`1[System.String]
11/27/15 13:00:10   ch[2]: 
Paul=System.Collections.Generic.List`1[System.String]
Problem solved - thank you!
