I have a base class library. In it I have a ccontainer class that is (no surprise here) based on the vfp container.

I have a test class library (testlibrary) that I have subsclassed ccontainer (testcon) and added a ccontainer (innerContainer) in. Then added another container (innerInnerContainer).

When I add the testlibrary to the Form Controls Toolbar and attempt to add the testcon class to a form I get the following:

Error loading file - record number 21. innerInnerContainer <or one of its members>. Parent : Cannot add INNERINNERCONTAINER. Class definition is cyclical

If you drag the control from the Project Explorer (Project Manager) the error appears during runtime.

In all the time I have been building apps, I'm not sure I have ever seen this happen. It was originally seen as a problem when my coworker was building a new class that gets loaded dynamically. He was building a UI that changes what is visible depending on what options are set. A pageframe changes pages depending what is selected. His is container with a pageframe and another pageframe on page2.

Error loading file - record number 25. InnerPageFrame <or one of its members>. Parent : Cannot add INNERPAGEFRAME. Class definition is cyclical

Is there a way around this?

Thank you, Tracy
