I am stumped.
After a long evening of testing, I have determined that having ANY line of code in the constructor of my class causes the application to display only a blank page. If I comment all of the code in the constructor everything works as you'd expect. If I uncomment even a single line, it doesn't matter which, I get a blank page.
In no case do Firebug or the logger report any kind of error. The application appears to load correctly but only a blank page is displayed.
I've tried deleting the entire folder with the compiled code (WebContent/outmineclient in this case) and recompiling.
I've cleared browser cache in both browsers.
I've restarted the computer.
I tried moving the external class into the main class as a subclass.
I've copied over all of the Isomorphic .jar files with ones from the download file in case they were somehow corrupted.
I'm out of ideas.
Am I missing something obvious? What can I do to troubleshoot this?
SmartGWT Pro 3.1p
Both Chrome and Firefox (with Firebug), whatever the latest versions are
Tomcat 7.0
Main Class
The class (MapViewer) is called like this:
If I comment out the line that calls MapViewer (and replace it with a plain canvas) it runs as expected.
Here is the class itself
None of the methods are currently called by the constructor. It runs if they are left uncommented just as long as everything in the constructor is commented.
It always compiles fine with no errors. Firebug shows no 404 errors or anything like that, only solid 200 codes.
Tomcat doesn't seem to be complaining about anything. Here is the console from a startup
And here's what the console tells me when the page loads
