I am trying to set up a category grid to sub category grid interface. I am having a difficult time getting the XML of the sub categories to feed right.

I think that finding out were the m object comes from or where it is created will help.

Here are some examples of its usage.

m.Categories.Kids
m.Categories = conn.LoadCategoryFeed(conn)
 m.categories.kids.count()

I have looked and can not find its source. Is it some magical built in object? :shock:

I appreciate any answers about this object or any tips on setting up a multi grid interface it is really racking my brain

"m" roughly corresponds to "self" or "this" in object-oriented languages.

It is a very clever hack that gives the impression of object-orientedness. It seems to me the implementation mechanics is: when invoking function in the form "someAA.aaElement(...)" (where someAA is associative array, aaElement is a key in it, pointing to a function) - before the function is invoked, someAA will be shoved in "m" so the function code has access to the sibling "attributes" from AA. And thus, we call the function "method". Not OO proper but gives you 80% of the functionality (Pareto fans anyone?).
