Following on from my previous question
(http://old.nabble.com/Some-Spring-Struts-questions-td28533505.html) about
injecting objects orthogonal to actions into the environment where jsps can
"see" them, I now have an interceptor that does what I want it do (Yay! -
thanks guys).
However, I'm seeing some peculiar behaviour that I don't understand fully.
The pertinent code in the interceptor is reproduced below. It does what I
expect it to do insofar as it sticks my "Stuff" object in a place that the
JSP can retrieve it using the MAGIC_KEY string. However, if I configure my
interceptor stack with this interceptor at the top, none of the other
interceptors appear to fire. If I put this interceptor last in the stack,
all of the others do seem to fire (well, the application works). Why should
I need to put this after all the params-prepare-params stuff?
public String intercept(ActionInvocation invocation) throws
Exception {
if (this.getStuff() != null) {
ActionContext ic = invocation.getInvocationContext();
if (ic != null) {
ValueStack vs = ic.getValueStack();
if (vs != null) {
vs.set(MAGIC_KEY, this.getStuff());
}
}
}
return invocation.invoke();
}
As always, any and all help/pointers gratefully accepted, particularly if
I'm doing something stupid!
Later
Andy
