Thanks for the reply, this is what I did to get it to work so far: I created a value object class to hold exactly the data I wanted for each row in the datagrid. When the php service returned the data I looped throught it and transfered what I needed to instances of my VO and then added those to a new array collection. That array collection I then bound as a dataprovider for my datagrid.
I put in an inline item renderer for the amount with a numeric stepper. The next step will then be to take the correct data from that array collection (item id and item amount) and transfer it to a php service that will save it in the order-table of the database. Since the grid and the ac are bound, I do not need to fire an event on focus out, I already have the data in the ac. I wonder how that solution might have worked when the user changes her mind and alters the amount many times on the products(?) --- In [email protected], "valdhor" <valdhorli...@...> wrote: > > First off, adding this one column datagrid and getting it to line up > correctly must be a pain.
