You Rock! I was stumped on how to do this app I was writing. I'm just learning flex/flash but I"m coming from alot of web development languages(all the way up the basic tree of languages then into php/mysql) So some things are still a bit confusing for me and the OOP is something I've been familiar with but never really applied in the languages I've worked with. Then here I am writing a flex based xml editor(which I can do easily in php) its amazing how much I was over thinking things in the first place and I didn't realize how simple it was until I read these tips of yours. now I have a really sweet little 'simple' editor thats given me a really good grasp of things throughout its creation. I'm using php for the backend. The part that helped me out the most was zeroing in on exactly what the e4x was capable of. While I was getting empty datagrids and couldn't figure out why, I seen your first comment about adding the 'resultFormat' to the HTTPservice request. That made my texarea editing box much simpler. and the file saves so much cleaner and neater. Then the comment that E4X expressions don't reference the topmost tag of the XML. I was having trouble populating a datagrid so that gave me an idea, I had one line: '{userRequest.lastResult.game.quote}'.I deleted ONE word and made it '{userRequest.lastResult.quote}', and saved and ran it. Everything loaded perfectly. As a side effect of having the text area AND the datagrid I was able to edit the document in the text area, and upon saving it updated the datagrid! Combine that with 'editable'. Its the best foundation I could ask for while learning flex 4 AND learning out to use php as a backend for it. Thanks again for putting these tips out for us. You just gave me my flex programming 'click' :)</p> Mike! You Rock! I was stumped on how to do this app I was writing.

I'm struggling with some XML issues and hoping you can help me out here. . .

I am trying to use the advanced data grid with my xml to group the data. I can not for the life of me figure this out can you help?

I have a demo with view source enabled here if you can take a peek at it and let me know your thoughts.

I"m trying to group data on a Category and then display the PathNFileName.
