Problem Description: The resolving of imported classpaths or packages breaks, when an inherited method is called just before the intstance tries to resolve a path. 

Steps to Reproduce: See the bug.zip attachment for the full description.

Actual Result: Imports break and can not be trusted. Produces a weird, hard to understand behaviour.

Any Workarounds: Use import XOR extends, never both.

Technical:
I looked into the cfusion.jar, to understand the behavior. These are the results, as far as I understood it:
- In the Class coldfusion.runtime.TemplateProxyFactory one of the methods that actually resolve imports is: 
-- public static File getResolvedFile(String fullName, NeoPageContext pageContext, String importList) (~ Line: 1201)
This method is used for resolving of returntypes, argumenttypes, classloading (new <import>Name()) and implicitUDFMethod types.

Package imports are resolved in Line 1299: 
> obj = getTemplateFileHelper(completeComponentName, pageContext, "");
Class imports are resolved in Line 1276:
>  obj = getTemplateFileHelper((String)specificImports.get(fullName), pageContext, "");

That method is the end point of the type resolving. A starting point is coldfusion.target.validation.CFCTypeValidator.validate() for type checks, another is coldfusion.runtime.CFPage._createObject() for classloading.

The bug could be around these methods, but at first I would look what happens, when inherited methods are called.

Sorry, if I talked nonsense about that stuff.

We bind import list inside function invocation which was overwriting parent cfc's import. For the fix we would internally cache this list before invoking the function and push it back on the current cfc object.
