MapScript, C#, delete_classObj exception

[Hallgren Johan E]

Hello

 

I use the 4.8.4 release of MapServer and I'm using csharp/Mapscript
option. The problem is that I could run a sequence of calls with no
problems and I can do it a number of times but suddenly I have problems.


 

The special things I do is that:

*         I use the same mapObj several times, in the same process, for
servral requests. 

*         I create inline features dynamically.  

*         I create layers for inline features dynamically.

*         I create classes for those dynamically.

 

After the image is created, I tries to clean up (restore) the stage to
how it was before the request. That where I have problems, in some
cases. 

 

In my log file I can read:

 

2006-04-12 20:23:44 mapscript_csharp

Object reference not set to an instance of an object.

 

   at mapscriptPINVOKE.delete_classObj(HandleRef jarg1)

   at classObj.Dispose()

   at classObj.Finalize()

 

It's really all I can say for the moment. After restarting the process
it runs thru as it should, no problems with cleaning up.

 

Any clues?

 

/Johan
