Re: [fw-webservices] Zend_Server_Reflection_Exception be more specific with your feedback...

Thanks for your response, however I had reviewed my code at LEAST ten times
before I submitted my question to the mailing list... Finally, I resorted
to copying my class to a new name and then, starting at the bottom, deleting
each method from the class. I was expecting to pinpoint which method was
causing the problem.

As it turned out, I continued deleting methods all the way to my __construct
- even then, the code still gives the same error. Lightbulb moment ensues -
my class is extending Zend_Db_Table and the error is obviously being thrown
in regards to some code in that class (or more accurately
Zend_Db_Table_Abstract).

I can see that this brings up a whole assortment of issues in regards to the
Zend_Json_Server - for example, a lot of return types from
Zend_Db_Table_Abstract are obviously not types that could be handled
natively by JavaScript.

So I guess the question has morphed into the following: how can I expose a
class through Zend_Json_Server that extends classes such as Zend_Db_Table?
