StreamID not found: Graphic column in a detail table, embedded browse form

[ashalkhakov]

When accepting a derived Add form with embedded Browse form for a table that has a column of type Graphic, I get the error "StreamID {id} not found".

I've uploaded a library to reproduce this behavior in Dataphoria:

Just register it, and then please do the following:

1. open the FaultyForm
2. enter some data (in particular, add a row into Table3 with an image
3. hit Accept

You should see the error message.

I've tracked it down to the process being disposed of deallocating all owned streams. The temporary work-around is here (patch made against Dataphor 3.0):

Is this an acceptable work-around?
