I am new to strut 2 though I have worked on struts 1.2.In one of the pexisting project jsp file I have following code:
Request is coming CustomerRelationAction.java which has method getCustomerRelations() and getRelationId().
here are the questions :-
I put breakpoint inside method getCustomerRelations().i see flow is coming four time inside this method. Two times at line 3 and another two times at line 4. As per my understanding flow should come only 1 time i.e at line 3. Once it completes getCustomerRelations at line 3 , should not put its value in value stack so that it can refer to it nextime it is refered (like it is being reffered at line 14 again)?
getCustomerRelations() method returns the list of CustomerRelationData objects where CustomerRelationData class also contains the getRelationId() method.Now at line 5 we are refering value="relationId at line 5. On Which object(CustomerRelationAction.java or CustomerRelationData), getRelationId() method will be called? even i am not sure will the list object CustomerRelationData will be present on value stack or not?If yes at which line it will be put in value stack?
Now the iterator completes at line 6.After that,now i refer the code <s:property value="relationId" /> again, On Which object(CustomerRelationAction.java or CustomerRelationData), getRelationId() method will be called?
To see the data in the value stack put your project development environment and use the tag in the jsp
ocjp 6 — Feeding a person with food is a great thing in this world. Feeding the same person by transferring the knowledge is far more better thing. The reason is the amount of satisfaction which we get through food is of only one minute or two. But the satisfaction which we can get through the knowledge is of life long.

Thanks for giving valuable information. But as soon as i do the above settings i see below error on web page
Do i need to do some other other setting too for this? i am putting <s:debug /> tag after var relationshipData got evaluated i.e after }(see below line 6)
