Cheers!

I've got a field "A" and a field "B".

"B" has a tree view inside.

I want the "create" param of B.tree to be changed according to the value of A (True/False)

I could easily manipulate field B but, what I want is... inside B.

<field name="A"/>

<field name="B">

<tree editable="top" create="true">

    <field name="whatever"/>

</tree>

</field>

Any bright idea? :)
