Uninstalled, reinstalled VS2008 w/all updates - reinstalled ECO5 - FIXED !!

So, I guess my VS was the issue, sigh.

[quote][b]Jonas Hogstrom (2009-04-28)[/b][hr]Normally the EcoDataSource will be configured so that it adds a key column called "ExternalId", and when you connect a gridview or some other databound control to this datasource, it should set its DataKeyNames property to "ExternalId". If this property is changed to some other value, you will get an exception when you try to perform an update from the component since the Datasource can't tell which row you updated.[/quote]

Nothing manually changed at all, ExternalID is there - the second time it happened I was using the default Class1/Attribute1 right after starting a new ECO5 solution w/xml persistence, generating model code, building solution, running xml autoforms. Edit works fine, but update does not.

"There is no key field defined in the UI component" ?

Joe Hendricks — Thu, 23 Apr 2009 23:26:34 GMT

Asp.Net content form with a DataGridView - ExternalID and an AutoInc I added are there. Let's me Edit a record but I get this when I hit the "Update" grid command column.. ran through QuickStart7(asp.net) and couldn't see any missed steps. I tried removing the class's associations, regernated model, vallidated model, regenerated db scema(SQLServer2005), rebuilt solution..err still there. Restarted VS2008 - err still there on update.

Anyone else see this? Doesn't the EcoDataSource take care of the PK?
