Z,
Thanks. I'll poke around the state and related tags some more. After
my last post, I've convinced myself to poke around openLaszlo a bit
more.
Cheers,
Brian

Brian : I think what your after is state stuff:

Of course you can also do this too:
<text text="${classroot.message}"/>
In general:
Its quite amazing what you can do with laszlo once you learn it, the biggest
hurdle is the learning curve
I did this small application for a customer
http://www.lightburnbulldogs.com/site/ (See pictures on
left)
But I did spend about a month before that pushing laszlo to its limits. The
one thing I find annoying is the fact that they use XML for nesting the
views. This tends to make pretty big source files.
I havent used the grid object but you can easily make a view look like a
grid, which gives you much more flexibility (and readability) on how the row
is displayed for example
<view datapath="list" height="200" width="800" layout="axis:y">
<view layout="axis:x" datapath="row">
<text datapath="field1/text()"/>
<text datapath="field2/text()"/>
<text datapath="field3/text()"/>
</view>
<vertscrollbar/>
</view>
should (somewhat) work with the following xml
<list>
<row><field1>a</field1><field2>b</field2><field3>c</field3></row>
<row><field1>a</field1><field2>b</field2><field3>c</field3></row>
<row><field1>a</field1><field2>b</field2><field3>c</field3></row>
<row><field1>a</field1><field2>b</field2><field3>c</field3></row>
</list>
but then again I also knew suneido (http://suneido.com) who's language
structure and views are very similar (but without the XML elements) before I
started laszlo
There used to be www.mylaszlo.com which reportedly was a playground to
showoff your apps but it hasnt been up for a while (It would be great to see
it up again !)
