Passing parameters to getter methods?
Hi,
I want to call s:iterator and fetch a list by passing it an index. This list will be dynamically generated.
<s:iterator value="products[#index]" var="product" status="stat">
where I want getProducts(Integer index) to be called.
Is this possible?
Thanks
Chris

Hi thanks. Sorry. My iterator is actually nested within another iterator. It
is fetching products based on the value of the index in the first loop.
Thanks. I will try that.

Well technically it's not a "getter" since it takes a parameter but
that doesn't matter you can call any method on your action just using
the full name and calling it like in java.
<s:iterator value="getProducts(#index)" var="product" status="stat">
Now I'm not sure what you are trying to do with the #index syntax
since getProducts() will be called once and should return a Collection
or Array, it is not called on each loop of the iterator.
You may need a different form of the iterator tag.

You can do this without parameters. Write a setter for this index
property (to save it), and then in the getter you grab the saved value.
