Thank you Tracy for your answer,
You are probably right about the bad design of my application. I know that the dataprovider component is used to pass data and not complete object. However my case is a little bit different (maybe there is an other way to assess my issue...) because I don't want to display a basic visual compound. Each of the displayed compound has to do an additional task; in my case a remote call via a RemoteObject. The only way I found to display these "living" object was to build the object, then to store it in an ArrayCollection and finally to reactive it in the datagrid (relifeData). Thanks for the data() function. I didn't know what was triggered by the addition of items in my grid. --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > First, a dataProvider should contain data.
