Error while deploying with BTDF

Question

Hi
I am trying to deploy BT Solution using BTDF. I am getting following error:
error : Failed to deploy port type "xxxx".
Operation "xxxx" of port type "xxxx." refers to message type "xxxx.__messagetype_xxxxxx" which has not been deployed.
EXEC : error : at Microsoft.BizTalk.Deployment.Assembly.BtsPortType.Save()
at Microsoft.BizTalk.Deployment.Assembly.BtsArtifactCollection.Save()
at Microsoft.BizTalk.Deployment.Assembly.BtsAssembly.Save(String applicationName)
at Microsoft.BizTalk.Deployment.BizTalkAssembly.PrivateDeploy(String server, String database, String assemblyPathname, String applicationName)
at Microsoft.BizTalk.Deployment.BizTalkAssembly.Deploy(Boolean redeploy, String server, String database, String assemblyPathname, String group, String applicationName, ApplicationLog log)

I can build and deploy same project and Solution using normal VS Deploy.
I am not able to understand this. I need your help. I can not think upon it more have spend many days already on it.
