Issue: EDG 6.3.1 - Unable to export to any file format other than TriG

[Tim Smith]

Hi,

When I attempt to export to a file from within EDG, the export fails with the following error.  This happens for all formats other than TriG and does not seem to be dependent on Asset Collection type.

Note that I am using the TBC version of EDG not the server version.  Hopefully this is a problem on my end since I need to export a some test graphs to share with you for other things I'm seeing.

Hi Tim. I'm not able to recreate this issue. Is it possible you accidentally deleted  \teamwork.topbraidlive.org\ui\teamwork.sms.ttl?

If that isn't the issue, can I request additional information from you off list? 

Thanks!

Taryn

Hi Taryn,

The file you mentioned is present in the workspace.  

I have traced the problem to a project I imported from a previous development effort with TQ.  Ralph, Natasa, and I had created a Custom Configuration for TBL.  I believe this was a supported method for adding parameters to the TBL environment.  It resulted in the creation of a file with the base URI of http://customconfig.topbraidlive.org/CustomConfigBaseSchema.  Of course this file does not exist in my current environment, causing a failed import error. 

In addition, another graph is missing that causes the following error:

Failed to initialize SWP graph registry - please refresh files

The stack trace is below.  What's interesting is that, typically, missing graphs do not cause issues beyond warnings.  In this case, even refresh does not solve the problem.  

When I remove the project from the workspace, everything works as expected.

Thanks for your help!  I will resolve the missing imports and all the issues should go away.

Tim

Here, the missing import was in a .ui.ttlx file, that is, in the code that makes up the running EDG system. It's a more severe situation than a missing import in data, and more difficult to recover from.

I've logged an internal ticket to see if we can handle that better.

Thanks for the report.
