DMI Showcase Example - Error saving data

[chess]

Hi,

I am currently evaluating SmartGWT and I downloaded the latest SmartGWT Pro/EE 2.0 evaluation package. I imported the showcase sample and ran
the DMI example.

I noticed that when I add/update a record, the grid seems to get updated correctly, but I see the below debug error msg on the Eclipse console. If
I quit and restart the application, the additions/edits are all gone. Is this
a problem with the sample example or with SmartGWT EE verion? I haven't
touched the code - just imported the whole showcase project into Eclipse
and ran the example.

Thanks.

PS: It's the same case with version 1.2.1 too.

[Isomorphic]

Harmless - just means the server is discarding extra data sent by the client that does not conform to the DataSource and target bean. Notice it's only logged at DEBUG level, it's not a warning.

But it doesn't seem to store the data. If I quit and restart the server, the
entires I made are lost.

Expected. Read the source for the example, especially SupplyItemStore.java. The example exists to demonstrate persistence against a fictitious pre-existing ORM store. Unlike the other samples, this one does not persist.
