Saving SPARQL query results to file

[ChilliPeppers]

Hi,

Is it a bug or am I just not doing something correctly.

When I run a SPARQL query in the Query Editor I can click the little Floppy Disk icon and save my results to a file.

If I do this (saving to txt) and then come back, edit the query and try to save again, nothing saves. I don't get the dialogue to save the file, just nothing.

Restarting TBC is the only way I've found to run another query and save the results.

What am I doing wrong?

Thanks

Terry

Hi Terry,

which TBC version are you using? Is there anything in the Error Log?

(The issue sounds vaguely familiar so it may have been fixed in the
meantime).

Thanks,
Holger

Hi Holger

I'm on Version: 4.3.1.v20131101-1317R

Nothing in the error log.

Hi Terry,

sorry all this works for me, and I have no further ideas what could be causing this.

Hi Terry,

I encounter the same behavior and reported it before (you are on Mac right?).

The same happens when you import a file from the file system. It will work once, then you have to reboot.

Terry, it's not clear that you have enough here to reproduce the problem.  One tip is to use Model > Refresh all Caches and Views instead of a TBC re-start.

If you can get this to a reproducible procedure, we can look into it further.

Thanks,

[Terry Roach]

So I go and try and replicate it or test the refresh and...

... its working fine today.

Exact same queries on the exact same model.

Go figure!

Hi Scott/Holger,

It seems the problem is broader than just saving query results. I have a very similar issue with importing XSD schemas,

The first port works fine, I can browse to a folder and pick the files I want to import. However if in the same session I try another import clicking on Select Files does nothing, it won't open the window to browse for files.

And I also discovered that the button to draw a graph of selected rows in my Query Results is not responding either.

Does this shed any light on what might be causing the issue?

Would a reinstall be something to try?

Thanks

Terry

[Holger Knublauch]

It sounds like your system is quite broken. What operating system are
you using? Did a reinstall help?

Holger

Hi Paul,

Yes this is the same problem that I am facing (on a Mac yes).

It seems that any call to the Mac file system will work the first time but won't open the Finder again on a second subsequent attempt.

Holger I have reinstalled TBC but still same problem. 

Coincidentally I did upgrade my Mac OS to 10.9.1 (Mavericks) this past weekend. I wonder if this has anything to do with it?)

Terry

[Scott Henninger]

Terry, I have been using Mavericks (10.9.1) for some time now, but did not opt to upgrade Java, hence I'm still running Java 1.6.

As much as I've tried, I cannot reproduce your issue (and thanks for the clear description).  So perhaps you are running Java 1.7?

-- Scott

[Terry Roach]

Hi Scott

Yes I have upgraded Java, I am on 1.7.0_45-b18

The problem is very intermittent though. I can't replicate it myself at the moment. Yesterday however I was doing a lot of xsd imports and must have had to restart TBC about 25 times.

Terry

[Holger Knublauch]

The Eclipse platform that TopBraid is built upon is known to have low-level bugs with Mac OS, so I am afraid these issues may be really difficult for us to fix. We may need to mark this combination of Mavericks and Java 7 as currently unsupported until we have finished our migration to Eclipse Kepler. The latter is almost complete and we have Kepler builds here, but Kepler has other UI bugs that make us hesitant to publish it with TopBraid 4.4.

[Holger Knublauch]

Thanks Paul. Here is more information, confirming that this is an Eclipse bug with Java 7:

Holger, 

What do you recommend as a solution? Still doing dozens of TBC restarts every day.

This explanation of the bug provides some recommendations for application developers: https://bugs.eclipse.org/bugs/show_bug.cgi?id=420682. Does 4.4 provide any of the solutions mentioned?

Paul,

Thanks for your tip. Could you be a bit more explicit for us less technically competent, modelling types. How exactly do I find and edit this info.plist

I could find:

 /Applications/tbcme4.3.1/TopBraid Composer 

but not:

 /Applications/tbcme4.3.1/TopBraid Composer.app/Contents

I searched for info.plist and found a long list of them, but they all seem to belong to Microsoft Apps, none for TBC

Thanks

TBC 4.4 will be based on Eclipse 4.3 (Kepler), and we are working towards a release early next week.
