I'm working on modifying the screen widgets to support Dojo (or any
other third party library). I set up the widgets to get their rendering
classes from a factory method instead of using the new operator. The
factory method uses the ObjectType.getInstance(...) methods to create
the class instances.
Everything works great except for one thing. Some of the rendering
classes have constructors that take
javax.servlet.http.HttpServletRequest
javax.servlet.http.HttpServletResponse
arguments. When I use the request and response objects found in the
screen widget context as arguments for the ObjectType.getInstance(...)
method, an exception is thrown - because the objects don't implement the
correct interfaces:
java.lang.NoSuchMethodException:
org.ofbiz.widget.html.HtmlFormRenderer.<init>(org.apache.catalina.connector.RequestFacade,
org.apache.catalina.connector.ResponseFacade).
Those classes implement the javax.servlet.ServletRequest and
javax.servlet.ServletResponse interfaces - which are the super
interfaces of the ones needed for the constructor.
I'm stuck. I don't know where to go from here.
Any ideas?
