I suspect _rowclass really needs to be a class, not a tagname. Try
_rowclass="lz.mygridrow". The fact that it starts with _ indicates
that it is an internal property, so you really need to know what you
are doing to use it. The fact that the recursive implicit include of
basecomponent stopped working sounds like a bug that should be
reported at jira.openlaszlo.org.

Hey Dave, try this simple addition:
<canvas>
<include href="base/basegridrow.lzx"/>
<class name="mygridrow" extends="basegridrow"/>
<dataset name="weatherdata" request="true" src="http://www.laszlosystems.com/cgi-pub/weather.cgi?zip=73003

I added that and it compiled....doesn't seem to print the double
click message, but it compiles.

When I needed to add some functionality to a grid row, instead of

This worked fine in 4.0.7. When I recently upgraded to 4.0.12 this
broke. I got the compilation error:
base/basegridrow.lzx:4:55: undefined superclass basecomponent for
class basegridrow
I understand how my locally declared class might not see the new
super class 'basecomponent', but was this an intentional change?
Or a bug?
Test script below.
Thanks,

Works in 4.0.7. Errors in 4.0.12
