Collection Editor

[Juan Romero]

Hey guys,

I am building a web control. Can someone give me a sample snippet or
explanation on how to use the collection editor to add/remove items to my
control's collection or array?

I am currently using an array to hold a number of items of a class X, I am
able to make the collection editor appear (ellipses button appears on
property, upon click, collection editor window comes up), but when I open it
again, all my items are gone. It looks like it is not saving back to the
class property.

Thanks!
