I am trying to
one-way bind a custom component to a complex actionscript
data model (the complex data model actually represents a c#
So, I have an complex object X of custom type
datasetstored in my model. I also have a custom component
with property Y (also type
The problem I am having is that when I bind the property Y of
the custom component to the complex object X, the object is passed
by reference, not by value. So in fact, it is not creating a 1-way
binding but in fact simply pointing property Y at X. So any changes
in X are seen in Y and any changes in Y are seen in X.
This is not what I want. I would like changes in the model,
X, to be seen in the view Y, but changes to the view Y not to be
seen in the model X, hence the need for one way binding.
I realise that Flex, by default is one way binding, but
usually you are binding value-type items such as strings to labels,
not complex objects to complex objects.
Binding an advanceddatagrid's dataProvider to an
arraycollection has exactly the same effect, as an arraycollection
is passed around by reference, not by value. So any changes you
make in the datagrid are immeidately made to the arraycollection as
Does anyone know of an alternate solution that could get
around this problem?
