[fusion-users] HTML in selection results?

[Paul Spencer]

Suggestion:

alter table properties add column PropertyReport;
update properties set PropertyReport = ...

ok, more seriously ... I think this will be something that has to be  
left to the new selection rendering code that Alan was working on -  
you can plug in your own JS function to render a selection.

What would be more useful in my mind would be a way to access the  
Extension contents when rendering so that you can have calculated  
properties be created in your own code on the client side.

Trying to do more stuff like this on the server with MapGuide is just  
going to get hairy (juggling types of fields, handling exceptions etc)  
and means more stuff in PHP that needs to be ported to the other  
languages if that ever gets done.

At least, that's what I think :)

Cheers

Paul
