[flexcoders] WebSercices, result, Array, DataGrid - Problems

[Francesco]

Hi,

I've a problem with my application.

I call a WebService that returns as result an array        -->
webservice.GetHeaders.result

Then I try to put the result into a dataGrid like this:

        <mx:DataGrid dataProvider="{webservice4.GetAllHeaders.result}"
width="100%">
                <mx:columns>
                        <mx:Array >
                                <mx:DataGridColumn  columnName="Date" 
headerText="date" />
                                <mx:DataGridColumn columnName="From" 
headerText="From" />
                                <mx:DataGridColumn columnName="Size" 
headerText="Size" />
                                <mx:DataGridColumn columnName="Subject" 
headerText="Subject" />
                                <mx:DataGridColumn columnName="UID" 
headerText="UID" />
                        </mx:Array>
                </mx:columns>
        </mx:DataGrid>

but the dataGrid still empty.

I've tried to put the result into a TextArea and I've receive:
[object Object], [object Object], [object Object], [object Object]

(I Know that the result should have 4 elements)

I've tested the webservice with a Test web page and it is ok.

Any suggestion?

Thanks!

Bye Francesco
