Reopening: need to enable select button in filters and make right click context menu work with selected nodes correctly. See gephi/gephi-plugins#124 (comment)

Bumping this issue, as it still restrains me to Gephi 0.8.2.

Any news?

Sorry still in the list to finish

Thank you, Eduardo. I'll test that right away.

Cool :) Please have in mind that the build needs to finish first before maven snapshot is updated, if you use them to test https://travis-ci.org/gephi/gephi/builds/266313464

Eduardo,

after testing around with it for a while, I ran into a problem which I was able to reproduce like this:

Check the videos:
https://youtu.be/2LnIAsBFXuQ
https://youtu.be/o3_tNiyZBtk
https://youtu.be/xCDAt41HPpw

1. Start gephi
2. Select "java.gexf" from welcome window. Make sure that the mouse pointer is NOT over the graph window when you generate the graph (avoid passing through the graph window or selecting ANY node)
3. Instantiate Filter "Topology/Degree Range". Do NOT click the "Filter" button
4. Click the "Select" button in the filter panel.

Result:

java.lang.NullPointerException

at org.gephi.filters.FilterThread.select(FilterThread.java:170)
[catch] at org.gephi.filters.FilterThread.run(FilterThread.java:123)

Another way to reproduce the error is:

1. Start Gephi
2. Select "java.gexf" from welcome window. Pass the mouse through the graph window area before the graph is created.
3. Instantiate Filter "Topology/Degree Range". Do NOT click the "Filter" button
4. Click the "Select" button in the filter panel various times, preferably in fast succession.

Result:

Thanks for the report! The last commit should fix this, please try later.

Will do. Thank you again.

Still occurs with Gephi 0.9.2-SNAPSHOT 201708231739:

Eduardo, please check that last one (https://youtu.be/aqjqCc2nqac). It's a bit different, but it really points towards Octree.

Are you able to reproduce these errors? Can I help with additional debugging information? I can run Gephi from source and put breakpoints wherever you want me to.

Oh thanks, there was another null pointer and I think some synchronization issues with concurrent octree usage. I added some synchronized marks and it does not seem to affect performance.

Can you please test this and check that performance is not worse with these new changes if you have some big graphs?

That seems to have solved the issue. Thank you very much.

Probably I'm not the most qualified to vote about big graphs, but for now I don't see any performance degradation.

Great! :)
