[Laszlo-user] Extending a base component

[Dave Miller]

When I needed to add some functionality to a grid row, instead of  
editing basegridrow.lzx, I extended the class like so:

<class name="mygridrow" extends="basegridrow" >
	<handler name="ondblclick" >
		Debug.write("2xclick");
	</handler>
</class>

<grid _rowclass="mygridrow" datapath=...



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,

Dave
