Hi there! I have a really simple question, can not find the answer :(
I'm trying to start a conversation on a second page after the user clicks on
a link in a view:<h:dataTable value="#{customers}" var="c"> .... <s:link id="startRentProcess" value="Start Rental" action="#{rentalService.start(c)}"/> My RentalService: @Name("rentalService") @Stateful @Scope(ScopeType.SESSION) public class RentalBean implements RentalService { @In(required=false) @Out private Customer customer; @Begin public void start(Customer c) { rental = new Rental(); customer = c; rental.setCustomer(c); }
The previous page is backed by a SLSB. When I get at the start, the Customer is null, not the one I've selected through the <s:link>
What am I missing? Do I need a @DataModelSelection?
Best regards
The easiest way would be to use a @RequestParameter variable in your SFSB, like this:@RequestParameter String customerId;
and<s:link id="startRentProcess" value="Start Rental" action="#{rentalService.start()}"> <f:param name="customerId" value="#{customer.id}"/> </s:link>
Seam will set the variable when the link is clicked, and you can retrieve the customer at that point. -

viniciuscarvalho May 3, 2007 4:02 PM (in response to viniciuscarvalho)Thanks, now, just to understand, why my idea did not work? I'm using the booking example as reference and its pretty much the same code.
Could not find why
hotelSearch.selectHotel(hot) works and
rentalService.start(c) does not... :(
Any ideas? -

viniciuscarvalho May 4, 2007 10:08 AM (in response to viniciuscarvalho)I'll give a try, but why on the examples (booking) we have this:
<h:column> <f:facet name="header">Action</f:facet> <s:link id="viewHotel" value="View Hotel" action="#{hotelBooking.selectHotel(hot)}"/> </h:column>
and it works? And on my version (as I stated before, I'm using the booking as reference, and almost everythng is the same)
it does not work?

delphi'sghost May 4, 2007 11:51 AM (in response to viniciuscarvalho)Can you show where the customers list is coming from, and what your syntax for the datatable tag is?
