Doesn't work in Grid

[guttormvik]

The attached example gives a client-side classcast exception.

If I were to guess, I'd say that the problem is that the Grid editor expects the connector to be an AbstractFieldConnector, while UploadField uses AbstractComponentConnector or something?

Seems that there are two separate problems then:

• UploadField doesn't fully behave like a "field"
• Grid should not insist on its editor components to be Fields
