Add new drop down list dinamically

Hi guru,

my problem:

I have a drop down list filled with binding for list item.

I have a button called 'ADD xxx', when i press via script i add new drop down

the script:

data.page1.prop._property.addInstance();

data.page1.prop.execInitialize();

inside the subform prop i have the drop down list.

the first drop down list the bindind is ok, in the other i add dinamically the binding don't work. the list is empty.

how to solve this?

best regards!    points for helping!
