Hi Campbell,

Thank you for your article!

I am interested in using your TreeFilter.

Would you please send me a sample? I would really appreciate it!!

Thank you!!,

Re sorting ArrayCollections:
Sorry to bother you, but I’m wondering:
Have you ever run into a problem w/ Flex 2 where (having properly set up your SortFields), the myArrayCollection.refresh() call appends a null element to your AC and the refresh blows up? I have that problem. I have isolated it and can replicate it using Adobe’s example (by adding a null array element into an array which is subsequently turned into an AC).
Any pointers you could offer would be much appreciated.
Best Regards,
Lisa

Hey Andi, Yes there are a few options available to you. I have sent you an email outlining the details.

Hi!

I ve read that you are hosting a flash player in a .NET application that does all the stuff that Flash/Flex can’t do. That sounds kinda interesting to me. I am doing the same thing with a product called “Zinc”. It hosts a flash player and I can put my swf in it plus write some dlls to do the native stuff (MIDI, Database, file processing, etc…) and call those functions from Actionscript. The cool thing of this Zinc-Projector is that the end user does not have to have Flash Player OCX installed. The downside is that this Zinc Projector is kinda buggy in some regards, which costs me some sleepless nights. Does not feel to good having 80,000 CD-Roms fabricated and theres a bug in the software… .
So I was wondering what kind of Flash Player you use in your project… is it the ActiveX one? or is it a different thing? I mean since they included the neat ExternalInterface thingy its quite possible for everyone to build a little bridge between Flash/Flex player and some custom C++, .NET or whatever function… just that the Flash-Player ActiveX control would still have to be installed, wouldn’t it? Well… if not that would be great news…

Cheers from Germany

Andi

Is there a way you can give some more advice on the TreeFilter. Maybe some samples…

Thanks in advance..

Hey Derek, Yeah I found it strange no one else had hit this problem before. Thought it would be a biggie if you didnt own the datasource.

Hi Campbell,

Thanks for the info. I’ve recently been playing around with exactly the same stuff.

I would add the that the filter function is implemented for the Tree control, as it is for any dataprovider. It just isn’t very useful for hierarchical data since it only filters the top level of the dataprovider.

Another way to solve this problem is to subclass the XMLListCollection and override the refresh method so that it recurses through the all of the data and filters out the items that you do not want. Then you just need to use this subclass as the dataprovider for your Tree,. Then you can use the filter function as you normally would.
