basically i have an array list of object that references another object for example i have a list of Invoice that has a variable of class Client. inside client contains the name of the client now how do i access client's name inside the invoice?
edit:
do i have to make a subreport every time i need to access the client's name?
edit 2:
i've got it. the expression given is basically the variable of that type class it represent which means you could access the models methods the same way you access them in
java
for example: i've got a client with a method/getter getName() to access it you just add .getName() to the expression like so $F{client}.getName() and with that we can access the method getName()
