Hi, i'm new to Stripes and I've been having problems using ForwardResolution
when I want to navigate to another page in my aplication.
The first page is index.jsp It uses a simple Bean (OsebaActionBean) that
checks if the form is valid. This happens when user clicks the submit
button.
If the form is not valid it sets errorMessageXX and stays on the same page.
Otherwise it navigates to another page that is a Calculator developed in
Stripes.
The problems occur when it navigates to calculator. It shows the Calculator
but when I click a button it displays an error message, that basicly says
that it can't find errorMessageXX in CalculatorActionBean
on index.jsp (but it is showing me the calculator that is in calculator.jsp)
I'm confused because of this strange mix (wrong page using the wrong bean)
I'm using RedirectResolution. If i try to use ForwardResolution it doesn't even
show
the calculator, instead it says that it cant find result in the
calc.PersonActionBean.
This also makes no sense because Calculator should use calc.CalculatorActionBean
where result is defined.
Can anybody help ? I will put the error and the code i think is relevant
below
