I never noticed it before because I can still reference the properties in objects in the array OK, just not the array itself. For example (projObj is the object of arrays and objects resulting from my webservice method call): trace(projObj.Content.Topics) //traces as undefined. Expected an array trace(typeof(projObj.Content.Topics)); //traces as object !?! and trace(projObj.Content.Topics[0]) //traces [object Object],undefined //but I expected [object Object], [object Object], [object Object] Finally: projObj.Content.Topics[0].TextAreas[0].HtmlText //traces the value I am expecting!!! ??? What's up? I can get the property values OK, but I cannot treat the array as an array as you would in Flash?

Or they need to hire some body like Anders Hielsberg. Even the basic stuff such as editor in Flash sucks. I can not believe that there is no company out there who can challange them. Not to mention their debugger, oh my oh my, people should be hanged for writing that thing. They may be need to drop their crappy ide and use eclipse as a platform, here is an idea!

My colleague and I are working on doing this sort of thing right now. How do I then use the array that is returned from the webservice? There is quite a bit of data returned that I don't need to display. So how can I sort throug it and select only the data I want to bind to my display components? Sorry - complete newbie.

I got the tutorial working that requests tips, returned as text. I am trying to get a datagrid to display and array of data but am having trouble getting it to work. Do you have to do anything more than the steps in the tutorial (for datagrids)? Tj Hi,
