during debugging my focus issue (https://developer.motorolasolutions.com/thread/1986) I had to change the config.xml file. I want to remove the xml Element <scrollbars>...</scrollbars>. So I suround the Element with <!-- and -->. The config.xml looks like this:
<ScrollBarsEnabled value="0" />
The result of this comment is a crash of RhoElements. The Application will be seen for 1 or 2 seconds and then RhoElements will disapear. When the bracket (< and >) are removed the app will start as expected.
The bug is if you have a '<' symbol within a comment. Though I've never seen it crash! That's really bad, Unfortunately this issue is still in 2.2 but I'll see if we can get it fixed in 2.3.
