Problems with property sheet when a bean changes shape.

Create a new non-visual class.
Add a string field and generate getters and setters.
Save this file.

Open a new Empty visual class.
Drop a button on the canvas.
Use Choose Bean to drop your non-visual class.
Save the Empty.

Switch back to the non-visual and refactor to rename the field.  Choose to
rename the getters/setters as well.

Switch back to the Empty.  Select the non-visual bean.  The old name is still
shown on the Property Sheet.  Setting a value generates a syntax error.  Close
Empty without saving.
Open Empty again and select the non-visual bean.  The property sheet is empty
and the error below shows up in the .log

The only way to fix this problem is to close and re-open the project.
