bean attributes not displaying - please help
I have a jsp page called 'customer.jsp' with a class call 'CustomerForm' which extendes ActionForm.
I have cut and paste my mappings and listed them below.
The application flow is such, that I have a link with a URI of /searchCustomers.do?action=Search. This action calls 'CustomerSearchAction' which initializes a 'CustomerForm' with null values for all the attributes except action, that's defaulted to 'Search'. That works fine.
When the end user completes and submits the 'CustomerForm' form, I construct a query that returns a list of customers matching the submitted criteria. 'Customers' is a class which contains a Hashtable of 'Customer' objects. This is accomplished with 'CustomerListAction' and forwards to 'customers.jsp' which presents the results in a list. I have a 'LinkCustomerTag' class which builds links within the iteration of 'customers' on the 'customers.jsp' page. The link looks like this: '/editCustomer.do?action=Edit&custNum=10' where 'custNum=10' dynamically changes throughout the iteration based on the current 'customer'. This works fine too.
I select one of the links in the list which maps to '/editCustomer' (see below) and calls the 'CustomerEditAction' class where I copy the properties to the instance of 'CustomerForm' and 'forward' to the 'customer.jsp'. This is where my problem is.
****** The form is blank. ******
I have lotts of comments in my code and can see that 'PropertyUtils.copyProrerties(customerForm, customer)' is getting called. I even modified the 'PropertyUtils' class to log the properties being copied within the 'Enumeration' in the 'copyProperties' method. You can see these values being copied into the 'ActionForm' but when the 'forward' is called and the 'customer.jsp' is displayed, it is empty.
Please help...

Thank you...
True, it is configurable, I see that.
So the ActionMapping object's getAttribute() method returns the name of the
'key' used to store the form bean, in this case an if block is used to
return the scope first, which determine where the form bean, references by
this mapping, passed into the perform method, has been stored.
Is that right?

Re: Solution: bean attributes not displaying (please comment)

Actually, the getAttribute() method returns the name of the attribute used
to store the form bean, not the mapping. The mapping is maintained
internally within the Struts controller, and is not saved under an
attribute.
Also, the form bean may be in request scope or session scope. This is
configurable in struts-config.xml.

Re: Solution: bean attributes not displaying (please comment)

The struts documentation indicates that 'mapping.getAttribute()' returns the
mapping name. In the case of the perform method in an Action instance, this
is a passed in property.
Therefore, 'request.removeAttribute(mapping,getAttribute())' removes the
stored attribute from the request context where attribute is the name of the
mapping.
This would have been stored in the request context in some previous step.
However, in the case that the mapping.getScope() doesn't return 'request' it
is removed from the session scope.

Solution: bean attributes not displaying (please comment)
Posted by Martin Zaidel <ma...@cortexebusiness.com.au>.
Got it: My problem resided in these lines of code in perform() (which I
copied from an Action class in the struts-example):
if (mapping.getAttribute() != null) {
if ("request".equals(mapping.getScope()))
request.removeAttribute(mapping.getAttribute());
else
session.removeAttribute(mapping.getAttribute());
}
So my question to the list is: what exactly are these lines doing?
Thanks,
Martin

Re: bean attributes not displaying - please help

Thanks for your reply...
I guessed that was the problem. I don't see the new instance being created
in my log file. I also have a fully working struts demo, which does not
display this behavior. What's up with that?

Re: bean attributes not displaying - please help
Posted by Martin Zaidel <ma...@cortexebusiness.com.au>.
I also have this problem, but alas, no solution (as yet). I've even
tried
in struts-config.xml to set the scope of the actions to "session", and
have explicitly
added the form to the session within the Action's perform(). I, too,
can see the form properly populated. However, when the form's jsp is
called, a new Form instance is instantiated----thus, the displayed form
is blank.
Any ideas?
