Hello,
I've created a uml 2 model several times and each time the .uml file's contents get deleted. All the packages, components, classes and their associations are deleted by MyEclipse. The file size shows as 1k when this occurs. What can cause this problem?
Thank you

larryflood,

Can you answer some more questions?

1) Please go to MyEclipse > Installation Summary > Installation Details and paste the information here for me
2) Can you create a new workspace and check if the issue persists?
3) Can you start MyEclipse using -clean and then check if the issue persists? Here is the information on how you can go about it.

4) The .log file is located at <workspace dir>/.metadata folder. Clear the log file and then try creating the UML 2 model. Do you see any errors? If yes then paste them here for me.
5) Could you please list the steps you followed to replicate this at my end?
