swpEdit service _base restrictions?

[Mark van Berkel]

Hello,

I'm using version 4.5 and working on an interface that uses SWA forms to modify data that's stored in a Named Graph of TDB. The swpEdit service gives an vague alert "Server Error" after making the edits. The data is saved fine, but the error is shown to the user, the interface doesn't switch back to View mode. In browser console it shows "POST http://appdev.schemaapp.com/tbl/swpEdit 500 (Server Error)" at jquery.js:8105   I've narrowed it down to a point where if I change only the base graph for the resource form to a regular TTL file it works. When I switch to a TDB named graph it shows the error. 

Is there a restriction on the base graph? Can't be TDB named graph? Maybe the base graph ontology needs some properties? I'm not sure, hoping someone can help! 

Thanks again,
Mark

Mark, it is the case that TopBraid will require that a connector to the named graph is defined, and you use the base URI of the connector (which can be the same as the named graph is TDB).  The general issue here is that TopBraid, workspace is basically a named graph architecture to begin with.  So to point to another named graph back-end a connector is needed to tell the system the back-end's URL and the URI of the named graph.

So perhaps try creating a named graph and have the application point tot he connector's base URI.  If that's not it, some more detail will be needed to explore further.
