I’ve got a custom HTML file I use my app with (like in the reservr example), and it seems that window.handleParameters() does not get called in this case. I also tried adding a URI handler with no luck.
How do I handle GET parameters when using the app through a HTML file?
Unfortunately parameter handlers don’t work with custom HTML pages, but this functionality will be implemented soon.
For a workaround, you could either create your own component (both server-side and client-side) which would collect the parameters from the URL and pass them on to the server and further route them to the actual ParameterHandler…
…or you could extend the ApplicationServlet class and modify the “writeAjaxPage”-method which would generate the customized HTML code for your application.
