Simantics System Dynamics

Hi,

After opening an example model I don't see a model in the modelbrowser anymore, nor any symbols under the tab "symbols".

OS: Windows 7 Professional
Java: version 8 update 111

Hi,

Sounds quite strange, maybe there was a failure in the connection between the user interface and the underlying database...? If so, starting from an empty workspace should fix the issue. I'm assuming you're using 1.9.0.

Same problem here. Starting from an empty workspace does not help. Indeed using 1.9.0.

I'm using version 1.9.1.

Tried today a different workspace location, but with the same results.
In the errorlog I've found some entrys that may be helpfull:

Hello,

based on the trace you're trying to use a network drive for storing the workspace. I have no idea yet why exactly Lucene indexing can fail in this case. However, https://bugs.eclipse.org/bugs/show_bug.cgi?id=438813 shows a very similar case where the workspace has also been stored on a network drive.

Is it possible for you to try to create the workspace on a local drive instead of a network drive?

Hi,

I've made a workspace in the root of my C-drive. Although the log shows no errors, symbols and model are not shown.

John.
