The other day I disabled Silverlight add-on in IE9. Don’t ask me why I don’t really remember, and I prefer not.

Several days after that I started an out of the browser application, ClickTime which we use to report our hours. And I got a weird JavaScript error a la IE with a white window and the picture asking me to install Silverlight. I checked that it was still installed and it was, no problem.

There are some times in which you need to come to some extreme solutions. Having two days of trials without success to have a portlet running in a local Tomcat with Day portal I came to the following solution.

Shortly why I came to such a solution? I needed to work on some CSS on a portal solution, and the development cycle was taking too long. I had to commit to svn, run a teamcity build which deployed a war to weblogic to finally be able to test my CSS changes. Far too long.

Last week I had an issue in Visual Studio 2010 debugger in some projects only! When I was looking at the value of variables I was getting an error message saying “Unable to evaluate the expression”!

Searching on Connect I have found that someone else had the same issue! Not really a good sign, “Debuging (Evalutation) stops working at times - Unable to evaluate the expression”. I have the same configuration, same issue and can reproduce what is described:

Today I faced a nasty bug, a null pointer exception in a property databound to our WPF application. This had some nasty side effects, and for sure this part of the code didn’t had any unit test, too bad! For sure now it has.

The line of code was really simple
