Random errors from MarvinSketch when trying to save

Hi,

We have an MSketchPane embedded in a dialog. The whole application is launched from an applet. File -> Save As sometimes fails silently, with a stack trace on the applet console. After a second try it seems to work. I suspect a problem related to loading classes when lazily loading the necessary jars. It only seems to happen if loading a jar takes long enough. (I couldn't reproduce the problem running everything on a local machine.)

First occasion:

java.lang.IllegalThreadStateException

chemaxon.marvin.util.MarvinModule.load(Unknown Source)

chemaxon.marvin.common.swing.MolPanel.loadLoadSaveModule(MolPanel.java:4325)

chemaxon.marvin.common.swing.MolPanel.saveMolfile(MolPanel.java:4290)

chemaxon.marvin.common.swing.MolPanel.saveMolfile(MolPanel.java:4273)

chemaxon.marvin.common.swing.MolPanel.saveMolfile(MolPanel.java:4257)

chemaxon.marvin.sketch.swing.SketchPanel.doSaveAs(SketchPanel.java:2016)

chemaxon.marvin.sketch.swing.actions.SaveAsAction.actionPerformed(SaveAsAction.java:27

Second occasion:

java.lang.RuntimeException: java.lang.ClassCastException:

< our JDialog subclass that contains MSketchPane >

cannot be cast to java.awt.Frame

Could you take a look at this please?

Thanks,

Dear Pal!

   Unfortunatelly it is a bug on our side. I have fixed it, and it will be in our next patch release. Until that you can only embed MSketchPane to a Frame correctly.

Hi Balázs,

Thanks very much for the quick reply and evaluation! Looking forward to the patch.

Many thanks,

Pál

Hi Balázs,

Would it be possible to obtain the patch to fix this issue?  Looks like this is becoming urgent for our own product release, and unfortunately I can see no workarounds... so any help would be appreciated.

Thanks,

Pál

Dear Pál!

   You can download Marvin 5.12.2. Have you tried it? Does it still fail with dialogs? Do you get a new error message?

Balázs 

Hi Balázs,

Ah, so the patch should be included in 5.12.2? That's really good news! I didn't see it in the release notes, so I suppose not all minor changes were listed there. I'll try 5.12.2 then and see how it goes.

Thanks,
Pál

It was commited minutes befor the commit deadline, and skipped administration. I am sorry for this trouble.

Hi Balázs,

No problem, thanks again! I couldn't reproduce the error with 5.12.2 so far (but haven't done a very extensive testing -- and it didn't appear every time originally).
Unfortunately I've run into another problem (NullPointerException coming from ToolBarBoxLayout), which I orignally thought was caused by the same issue, but it's apparently not -- I'll post it in another topic.

Pál

The build of the next patch just have started, but we will investigate the new issue as well.
