DLMSDirector

Hi,

I'm testing the DLMS.AMI solution with the GXDLMSDirectory.
Whenever I try to capture and view the Profile Generic data I get a cast exception after refreshing the view:

System.InvalidCastException: Unable to cast object of type 'Gurux.DLMS.GXDLMSMeter' to type 'Gurux.DLMS.AMI.Messages.DB.GXDevice'.

This happens after the ObjectController returns the ListObjectResponse.

{SELECT GXObject.`Id`, GXObject.`DeviceId`, GXObject.`TemplateId`, GXObject.`Version`, GXObject.`ObjectType`, GXObject.`Name`, GXObject.`LogicalName`, GXObject.`ShortName`, GXObject.`Generation`, GXObject.`Updated`, GXObject.`Removed`, GXObject.`ExtraInfo`, GXAttribute.`Id`, GXAttribute.`ObjectId`, GXAttribute.`TemplateId`, GXAttribute.`Index`, GXAttribute.`Name`, GXAttribute.`Value`, GXAttribute.`Generation`, GXAttribute.`Updated`, GXAttribute.`Read`, GXAttribute.`TaskId`, GXAttribute.`ExpirationTime`, GXAttribute.`Removed`, GXAttribute.`AccessLevel`, GXAttribute.`Exception`, GXAttribute.`DataType`, GXAttribute.`UIDataType`, GXAttribute.`ExtraInfo` FROM GXObject INNER JOIN GXAttribute ON GXObject.`Id`=GXAttribute.`ObjectId`}

{WHERE ((((GXObject.`Removed` = '0001-01-01 00:00:00') AND (GXObject.`ObjectType` = 7)) AND (UPPER(GXObject.`LogicalName`) LIKE('0.0.98.1.0.126'))) AND (GXAttribute.`Removed` = '0001-01-01 00:00:00') AND (GXObject.`DeviceId` IN (SELECT `DeviceId` FROM GXObject WHERE GXObject.`DeviceId` = 1)))}
