Need some info on ListEdit
Hi,
I have a page which consists of 5 blocks(default) and each block represents a Bean.These blocks have a checkbox attached.There are two buttons "Add Line" which will add a block and a "Delete Selected" which will delete the selected blocks.
Can anyone guide me as to how this can be best achieved.I am looking at ListEdit component currently.Any pointers/pseudo -code as how to go about.

I recently did something like this. In my page, there is a form for entering
data, and if the user needs more than one reservation, they can add another
dynamically and fill it out. Any but the original can be deleted as well.
I've included the code below for you to look at. You'll notice I've just got
a HashMap of my slot because this has mock data--I don't have a backend to
connect to yet. Also, I didn't include the html, so if you want that, let me
know.
