I noticed something strange when filtering edges. This is what happens:
1) I have a graph with a "hypertext" edge boolean value (some edges are "hypertext", some other aren't)
2) I put a "partition : hypertext" filter
3) when I filter by "hypertext = true" or "hypertext = false", my graph disappears
4) when I filter by "hypertext = true OR false" my graph is back
This is what I understand: when I filter my graph by edges, each edge filtered disappears with its two nodes. It isn't what I expected, I think that hiding the edges without hiding the nodes is more relevant. Anyway it could be useful to choose the behavior you want. Isn't it ?
Filtering edges also filters nodes

Re: Filtering edges also filters nodes
Filtering edges should only filter (i.e. hide or select) edges and keep nodes untouched.
I'll look if there is a problem and keep you updated.

Re: Filtering edges also filters nodes
It is indeed a bug, I filled this bug report https://bugs.launchpad.net/gephi/+bug/522771
Re: Filtering edges also filters nodes
Thanks for the bug report.
I have a linked remarked, which this time may be a feature rather than a bug.
When I import a GDF and that some nodes miss, but are mentioned in edges, then "empty" nodes are created.
This behavior is new, since before Gephi was "forgetting" edges.
Both techniques are legitimate, but it may be useful to have the choice.
When I help my students to clean their data / to modify files, they sometimes just want to erase malformed nodes, and it's more easy if you don't have to erase also the edges...

Re: Filtering edges also filters nodes
I think this 'choice' is already in todo list

Oh yeah thx, didn't notice.
