New from the Agile Toolkit News site today, there's a new article looking at selectively rendering views in framework-based web applications, handling them as objects instead of just output.

Today - any desktop software is able to re-draw itself from a callback by operating system. However many Web Frameworks today do not keep track of objects and cannot selectively produce pieces of HTML code. I believe that ability to have control over objects on HTML pages is very essential to have in the Framework. Here is why...

He starts with a look at how desktop software handles things, then moves to the state of web rendering ("still in the 90-ties"). He talks about their better approach to things - creating a two-pass walkthrough where rendering is done on each of the objects in the page first and then those are passed to a "master parser" for overall display. A simple PHP code example is included. Creating an application with this approach makes performance, javascript integration and other templating features simpler.
