Bug Description


this looks like a pretty annoying bug:

I'm working with dynamic timeline data, which exists in the first place as a GEXF file (sample attached to this bug report). After loading the GEXF file, I can click on the timeline 'play' button, and the timeline slider works as expected - in the case of the data I work with, network edges appear and disappear as I use the slider. (In my data, only edges have timeline information - nodes are always visible.)

If I save this project as a .gephi file and reload the project file, however, the timeline functionality no longer works, and there doesn't seem to be any way to get it back. Any way to fix this ?

I'm attaching a GEXF data file so you can reproduce this issue. Here are the steps:

1. Load GEXF file into Gephi.
2. Click timeline 'play' button (green arrow), and use the slider - edges appear and disappear.
3. Select 'Save as...' from the File menu, and save as Gephi project file (.gephi).
4. Exit Gephi.
5. Open Gephi, and load saved .gephi project file.
6. Click timeline 'play' button (or try to start the timeline filter using the filters tab) - nothing happens...

Many thanks in advance,

Axel Bruns

Tested with trunk@rev2132, the exception occurs when opening the .gephi file at step 5:

Fixed in rev 2137, thanks to the recent improvements in serialization
