Wed, 08 Sep 2010 12:25:00 -0400

Wed, 01 Sep 2010 13:49:00 -0400

Sat, 28 Aug 2010 07:54:00 -0400

Earlier this week a user asked me to look into something odd with CF901's new multirowselect feature for cfgrid. If you haven't played with this yet, it is a way to enable multiple row selections in a grid. Unfortunately it doesn't quite work as adve... [More]

Tue, 24 Aug 2010 13:15:00 -0400

Watch out for this one - I almost didn't notice it. Today I went to add a new mapping. It just so happened that the mapping I added was one that already existed. The administrator correctly noticed this and gave me an error: No big deal, right...

Can a web action fire off an AIR event?

Mon, 23 Aug 2010 16:26:00 -0400

This was a great question that came in via a reader last week. Because of the nature of his business I have to be a bit vague. Basically he wanted to know if there was some way where a click on a web page could have some type of response within an AI... [More]
