Forgive me if I have missed something but here is what I seem to think about ColdFusion report builder after reviewing the latest ColdFusion 11 release.
The v11 is the same as v10.
Report Builder hasn't changed really since it was first released.
It still isn't available for anything other than windows even though ColdFusion and the popular IDES for ColdFusion are cross platform.
So with that I can't help wonder:
What exactly does Adobe want you to use for building reports within ColdFusion? Are they really wanting us to use something else? Maybe Jasper?
If I have a Mac then are they saying that even though they have a product (ColdFusion) that is developed to run on a Mac (because they want Mac users to use it I guess) then you can't develop reports.
What have I missed?
Report Builder was a Macromedia product that Adobe picked up in the boot sale. As far as I can tell, they've never indicated any interest in it.
As far as "What exactly does Adobe want you to use for building reports within ColdFusion?", perhaps the answer is "they don't care". Not least of all because ColdFusion was always a server-side product, and it was a bit of a weird decision for Macromedia to developer a tangential desktop product to work with it.
I don't mean to be dismissive when I say this, I just think everyone realised Report Builder was a poorly realised idea and dead in the water when it was released.
I imagine Adobe expect one to separate out the idea of "server side" and "client side", and accordingly use [any old desktop app you like] to create your reports, and simply publish them to a web-servable format for the web server (not the ColdFusion server) to deliver.
