Using rpc, you have to provide the fully qualified Java class name :
a.b.c.Class.
This is case sensitive.
Then the method name and then an array for the parameters.
The class called act like a controller and thus will be a singleton manage
automatically by the rpcservlet.
You don't have to worry about that controller instance yourself as it will be
generically instanciated on Java side by servlet.

we started before bind and are not using it, can't help here.

Set the model to the table before adding the table to any container. the table
won't be visible until you set all you want, including visible column.

Beautiful is writing same markup. Internet Explorer 9 supports
standards for HTML5, CSS3, SVG 1.1, ECMAScript5, and DOM L2 & L3.
