I installed Monox on Windows 7 using SQL Express 2012. I am running Visual Studio 2013. All folder permissions are set correctly according to the "test permissions" stage of the install. I am using IE 10 as my browser, but the behavior also occurs in Chrome.
When i run the portal, it runs perfectly well until I try to access the pages in the portal administration. It errors out with the error "Value must not be null for Controls and Behaviors". Its an error thrown in the function Sys$Component$create on the parameter 'element' which is null.
The line containing the exception is:
if (!element) throw Error.argument('element', Sys.Res.createNoDom);
This behavior occurs with version 4_9 but I also downloaded and installed the most recent overnight build and it does the same thing. Essentially this halts anything I can do with the portal because I have no ability to manage the pages. Any help would be appreciated.
