Here's what I mean by it crashed, I click an Anchor which is tied to a
server call. During the RPC call -
com.google.gwt.user.client.rpc.StatusCodeException is thrown. Which
causes the "GWT Development Mode" to create a new Session, reloading
the app as if I just launched it (entering the onModuleLoad() of my
main class). Remember this happens where the ONLY difference is using
"Anchor" instead of "Hyperlink" in the declaration, the rest of the
code is identical.
I am doing something a little dangerous, I use onModuleLoad() as my
entry point for each web page, even though there is only ONE module
for the application... Let me repeat to be more clear, I click a link
which calls myOtherClass.onModuleLoad() which draws the screen how
that "webpage" should look. I should probably make a new method name
instead of overloading onModuleLoad() and see if that is what was
causing the Anchor class to throw during RPC.
