Hi,

I have the latest version of MySql, LLBLGen and the CoreLab thingy but I'm getting this error from the following code...

EntityCollection<VwSkinEntity> collection = new EntityCollection<VwSkinEntity>();

DataAccessAdapter adapter = new DataAccessAdapter();
adapter.FetchEntityCollection(collection, null);

Any ideas?

Cheers, Ian.

are you sure is only this:

EntityCollection<VwSkinEntity> collection = new EntityCollection<VwSkinEntity>();

DataAccessAdapter adapter = new DataAccessAdapter();
adapter.FetchEntityCollection(collection, null);

Please try regenerating your entities.

The problem seems to be that when I add the view to the designer there's no information about the view. '#of fields' is '0'.

Here's the view..

DROP VIEW IF EXISTS `sdn_digital_signage`.`vw_player_aw_schedule`;
CREATE OR REPLACE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `vw_player_aw_schedule` AS

select

max(`tbl_player_aw_schedule_feed`.`PlayerID`) AS `PlayerID`,
`tbl_player_aw_schedule_feed`.`ScheduleID` AS `ScheduleID

from
`tbl_player_aw_schedule_feed`

group by
`tbl_player_aw_schedule_feed`.`ScheduleID`;

Would you please check the Designer output window for possible errors when refreshing the catalog.

Ahh, I did a full refresh instead of an unattended and noticed that the 'views' checkbox wasn't selected. So I checked it and now the fields appear when the view is added.

So I don't think the view should have been added to the list of views during the unattended.
