Hi Aaron,
It appears to me that a key to generating RUI applications is to embed RUI widgets in standard HTML pages, use a template engine to dynamically generate pages, then have high-level RPG procedures asynchronously supplying properly formatted data streams to data-bound widgets.
Here's an example that you will relate to, since it was derived in part from the Pet Store Item List that you provided in your RPGUI library.

Note that a JSON formatted data stream is generated in the RPG "loadgrid" subroutine by mapping the internal record buffer "itemrec" to a JSON array object. The jsoRecWrt() procedure is a remarkably streamlined procedure for mapping fields from any internal record buffer to a JSON object. It really streamlines the interface for the programmer.
You can compare that to the jsonNode() procedure in PowerExt, which in contrast requires developers to write substantially more lines of code.
Nathan.

Has anybody else had exposure to PowerExt (www.PowerExt.com)? I was just
informed of it by a gent needing RPGUI support. It is also GPL v3. It has
similarities to RPGUI as it is RPG based and interacts with ExtJS. It is
more mature than RPGUI at this point.
I loaded it on my machine and see that it has a very clean code base (some
of the cleanest code I have seen), though the doc blocks lack descriptions
of what the code is actually purposed for (not a huge deal, but definitely
slowing me down).
Of particular interest to me is how the ExtJS forms/fields are generated.
If you install it you can see what I mean in POWEREXT/QSRC,PXAPICDM.
The other prominent piece is localization (something I don't always have at
the forefront, but have learned enough times the hard way that now it is
definitely on the priority list).
Best I can tell it was first introduced in mid Oct 2009.
