Hi list,

I'm planning to do maintenance work on an existing ontology (in RDF format). In TopBraid Composer (v6.0.1.v20180831-1223R) I've created a new project, and dragged the RDF file into the 'Project explorer' window, and into the project folder. I've asked to make a copy, rather than reference the file where it came from. So far so good. The imported file is about 10Mb of size. When I open the imported file it loads up well, but TBC throws an error "stack overflow" when I try to save. Even if I make non-existent changes to the file, such as adding and removing a class, this error is thrown. So it certainly doesn't relate to the changes I make, but rather to the serialization process of what is loaded up in TBC. Below is the log.

Can anyone suggest a solution? I've been wondering if it could relate to things like file size, use of special characters or circular classes. But in all cases, I would expect TBC to handle the error differently than failing to save with a stack overflow.

Regards,

Rutger
