Hi !
I created a new component for my project. One of the properties of this
component is a collection of a class created by me, I called this class
"UmaTabela"

The class (each element in collection) has two properties, one of them is
another class, created by me. I called this class as "Mapeamento".

I used desinertimeserializationvisibility in collection property, and I
created a typeConverter to return instance descriptor for both, "UmaTabela"
class and "Mapeamento" class.

The problems started because "Mapeamento" class needs a initialization
sequence, so I implemented IsupportInitialize.

But VS didn't recognize the implementation of IsupportInitialize. VS
serialize the class and it's properties in the code, but didn't make the
calls for beginInit and endInit. I think this is because the class is inside
another class that's inside a collection.

To solve this problem I tried to create a custom codeDomSerializer to add
BeginInit and EndInit calls. After some trys the most closely I get is to
put the custom serializer in UmaTabela class. The problem is that Mapeamento
variable is created as a local variable inside initializeComponent and the
custom serializer generates a "me." keyword in front of method calls, like
this "me.mapeamento1.begininit", so this doesn't work because mapeamento1 is
local variable, not form variable.

So, some questions at this point :

A) Is there any other way to expose IsupportInitialize in this case without
create a custom codeDom serializer ? How to force this interface to be
regonized by VS ?

B) How to control if the components variables will be generated in form
level or in initializeComponent level ?

C) How to take out that "Me." keyword generated by the custom codeDom
serializer ?

P.S. : When Mapeamento class inherits from system.componentmodel.component
the "me." keyword appears. When it has no inheritance, "BeginInit" and
"EndInit" calls apears alone, with no object.

P.P.S : Sorry by my bad english and thanks a lot for help !
