Re: Issue: using logic:iterate to display rows and html:button to dis tinguish one of them

[WongTseng <wa...@gmail.com>]

It's bacause you have more than one hidden elements with the same name,so
whichever
row you choose to delete, your action will recive an array of parameter
values with the same  parameter name. That's the reason why you always get
the id of the first row. I suggest you to use a radio boxs to replace the
hidden elements,and only one delete button is enough.
