I recently upgraded to 11.2 and found that my styles to add a checkbox to the record selector no longer handles null values. When there is a mixture of true and false values then the checkbox in the header should be a square, and that used to work in previous versions. In fact, the first picture in Josh Smith's blog shows it correctly.

The problem is easily visible in the feature browser on the "Checkbox in Record Selectors" page. see screenshot.
Hello,
I am just checking if you got this worked out or you still require any assistance or clarification on the matter.
Thank you for your post. I have been looking into it and I tested the code from the sample in the Feature Browser and the one Josh Smith provided both with the RTM and latest service release of 11.2 and it seems like that everything works ok on my side. I suggest you download the latest service release of 11.2 by logging to our web site and going to My IG \My Keys and Downloads and if the issue still occurs, could you please send me an isolated sample project where it is reproduced, so I can investigate it further for you.
Looking forward for your reply.
