Considering your code is based on a local "firstTime" variable, is your
bean session scoped? If the bean is request scoped, "firstTime" will be
initialized similarly during each request.
FYI, instead of refreshing each hidden field separately, you could use
the following code, instead. Note that when the component id is not
provided, the refresh function acts as a reset. That is, the component
will be redrawn only using values set server-side.
newurlNode.refresh("toplevelform:j_id26:var1,
toplevelform:j_id26:var2,
toplevelform:j_id26:var3");
