We have an XSD that has a numerous amount of properties that need to be set. We have placed all those properties on the browser, so when the user submits those values I want to plug those properties into the jaxb object. So instead of coding a bunch of setXXX, I wanted to do in such a way that if the xsd changed all I have to do is change the GUI and give that gwt gui object a name that maps directly to the xsd.
So the xsd has UserName The gui will have a g:Textbox name="UserName" Then in the code I would call the reflective method. As I typed this I guess regardless there would be no way to do this on the client side. So now I am thinking that I could just send the widget to the server and the server could do all the reflection it needs. Pseudocode for the server side String someMethodCalledAsync(Widget t){ for ( Node n : t.getElement().getChildNodes() ){ if ( n )//do reflection to see if this object has a getName method. if so we can use it and do an easy map to the jaxb object. } } On Apr 29, 10:08 am, Sripathi Krishnan <sripathikrish...@gmail.com> wrote: > GWT doesn't support reflection or dynamic method invocation for performance > reasons.
