So I spent the last few hours re writing my module since my last one gave me a null pointer exception. Everything worked fine when I turned it off last night. Now I started on it this morning and bam…another null pointer exception! I can play the module but not edit it anymore. Someone please help me! Is it something Im doing wrong or is there something I am missing? I dont want to have to rewrite all that data again.

Also I notice it talks about a build file. How do I make one so i can easier edit my module. Again here is the error log created by this mod.

PS after it gives me the null pointer excetion it says that the mod is already opened, but i dont see it opened anywhere.

I don’t know how to read a log file but the first thing I noticed right on top is the note “Unable to load image”. Have you included an image for whatever it is you’re trying to load?

Is it JPG, PNG or GIF?

I tend to use all PNG’s for my mod. I’ve found them to be the most trouble free.

Neumannium · June 10, 2008, 2:10pm

I’ve had the same issue.

I found that if I open the module (for play, rather than editing) it opens.

Then, after I close it, it will open fine in edit mode.

It may just be 3.1 beta 2 that’s the problem at the moment. There are some mods that can’t be opened for editing in the current version …mine included. I’ve been following the threads and it appears they have a handle on it and should be fixed in the next release. Have you tried using a previous version of Vassal?

Until they get the kinks worked out, I’m still using 3.0.17 for all my editing and that’s working fine.

tried it and it still gives me the same error[/i]

emaluzer · June 10, 2008, 3:57pm

I dont think I included and image in player hand map could this be the problem? if so can i fix it or do I need to start over. IF i can fix it how?

DrNostromo · June 11, 2008, 3:20am

It could be. It’s been my experience that usually Null Pointer Exceptions simply mean that you have something in your mod that is pointing to something that isn’t there. So, yes, it could be a missing image …although I haven’t seen it cause a problem where the mod didn’t load.

I don’t know how to go about fixing that. Best to let the Vassal gurus tackle this one.

Brent_Easton · June 11, 2008, 4:06am

Is your module available for download somewhere? I’d like to have a closer look at the NPE.

Thanks,
Brent.

Brent,

I have noticed too the same problem using the Last Tannhauser Module (available in the Module Section)

The error message appears with the 3.1, but not with the 3.0.17 …
