Hi Michael,
Thanks for your reply.
For the Ajax solution...In the files that I attached. ....What I am tring to
do is loading the model when the page loads up first time.
At this time the Pojo is empty so model has no values ,which means there is
nothing to iterate so list appears empty.
Now, my challenge is when user click the "search" button and tries to
search...then I have to get the Pojo and call DAO to get the results and
wrap the results in the same model(that I used while loading up the
page)...so that same model gets new values and then update the
ListView/DataView without the whole page refresh.
But, I am unable to assign the newly returned values by DAO to old model
because it says "final variable cannot be referred from inside"
Do you think my approach is correct towards the problem?
Any suggestions?
Thanks,
RG
