importing preferences does not work

[ilippert]

JabRef 4.0-dev--snapshot--2017-07-31--master--ed815b4a9
Linux 4.11.11-300.fc26.x86_64 amd64
Java 1.8.0_144

1. export preferences

2. reset preferences
   saves preference file works

3. import preferences

Issue: when attempting to activate "import preferences", no import dialogue shows up.

Same happens at
JabRef 4.0.0-beta
Linux 4.11.11-300.fc26.x86_64 amd64
Java 1.8.0_144

I can confirm this on Win7. No import dialog and also no messages in the log.

@Siedlerchr There were changes to the file system dialog, right?

[Siedlerchr]

You have to restart JabRef after resetting the preferences to import new ones., as the dialog says.

The problem is that there's no dialog. I haven't done anything with my preferences, but when I hit the button "Import preferences" then nothing happens.

It's not necessarily related to your changes. Maybe that dialog is broken since a long time.

[Siedlerchr]

After a restart of JabRef the dialog appears again. I look into that

[Siedlerchr]

Found the bug, the exportPath in the FiledialogBuilder is null and Files.exist(null) throws an NPE

[Siedlerchr]

Thank you for reporting this issue. We think, that is already fixed in our development version and consequently the change will be included in the next release.

We would like to ask you to use a development build from https://builds.jabref.org/master and report back if it works for you.

works, thanks a lot!
