Errorhandling!

Hi, I need some help with error-handling. For the second time now my whole processFlow suddenly freezes and then dissapears. I get the following system console -code repeatedly:

"

exception: Exception caught in TreeNode::callMemberFunction() main function. Throwing...

exception: FlexScript exception: Exception caught in TreeNode::callMemberFunction() c++/dll execution. Throwing... at VIEW:/active/MainPanel/BackPanel/SplitterXPane/SplitterYPane/SplitterXPane/TabPane~2/TabControl/ProcessFlow>eventfunctions/OnDraw c: VIEW:/active/MainPanel/BackPanel/SplitterXPane/SplitterYPane/SplitterXPane/TabPane~2/TabControl/ProcessFlow
"

How can I solve this? It will be timeconsuming to build the model from scratch again. I have added the file in question to the post. JobShopRoute V1.0.fsm


In advance - thank you!

Do you have a previous version saved to which you can revert?

It appeared to be a problem with the "Release Resource1" node in the process flow.

Could you describe to me how you found out and solved it? For me the entire processflow was hidden/gone and I could only orientate around in the model..


Would be nice to know when something like this happens in the future :)
Thank you in advance!

This may not help in every situation.

  1. Close the Process Flow view
  2. Explore the Process Flow object in the tree under Tools/ProcessFlow/<YourProcesFlow>
  3. Look for anomalies

At the bottom I found this:

..which doesn't have the structure that an activity should have - so I deleted it and found that fixed the drawing.

Generally I'd advise against editing in the tree like this but sometimes you can destroy parts of a model in order to discover the offending item - just be careful you don't save over your complete model.

Another question here is how this happened. If you have any information on steps that could repeat this let us know so we can protect against it.

The problem occured when i was clicking and dropping different objects from the library to the process flow model, like "travel", "Resource" etc.

I don't know exactly how it happend, but suddenly the program froze, and shortly afterwards the entire processflow model was invisible or gone...
