I assume you are using a Layout, since you want to use Navigations. I will
give an example of something that I believe will work, but I am sure I will
mess up some of the method names since I do not write things this way
generally and I do not want to look up several things to give a simple
example.
myLayout
{
public doBuild(data)
{
PrintWriter out = data.getOut();
out.write("<table> ...some more hml");
NavigationLoader.getInstance().exec("Nav1", data);
out.write("some more hml");
NavigationLoader.getInstance().exec("Nav2", data);
out.write("some more hml");
ScreenLoader.getInstance().exec("theScreen", data);
out.write("some more hml");
NavigationLoader.getInstance().exec("Nav3", data);
out.write("some more hml...</table>");
}
}
The doBuild methods in each of the navs and screen will get the output
stream and write directly to it. they can return null.
theScreen's getLayout method should return "myLayout".
Now once you get this to work, please give up on using this as a method to
build web apps. Use WebMacro or FreeMarker. They completely hide the use
of ECS within Turbine.
