as shown in the attached image, if I want to access the value of the textbox with value "value2" (the textbox in the second row after the "add" button"), how to do it as seem there is no a specific name to access it.
maybe my design is poor, any better method suggested? in reality, the listbox is used for user select "searc field", and the textbox is for user enter search value for that search field.

I think you mean add a getter and setter in CompositePanel, but the problem is how to access it in HATestPanel?
as I don't know the variable name of each CompositePanel.
just like I click the button three times, then what is the variaible name of these 3 compositePanel? although in each click handler its name is compositePanel.

Store them in a separate list or iterate through all child widgets of your HATestPanel using FlowPanel.getWidgetCount() and FlowPanel.getWidget(int index). For each widget check if its a CompositePanel, cast it and call its getter to get the value.

In other words: variables are a mean to give name to things; fields are just variables with a distinct scope (object instance instead of local to a block or method). If you need/want names for things, it's up to you to give them such a name.
Sorry, I cannot catch your idea, in my clickhandler, the variable name is compositePanel for each click, and then add to the flowpanel, but if I press the add button three time and then outside the add button, how to refer the name of these three compositePanel?

But there is still some problem, if I want to add a delete button after each row, is it very difficult? Or the easier method is add a checkbox before the listbox in class CompositePanel and then add a "delete" button (one and only one for the HATestPanel, not per row) to the HATestPanel?
I see this forum attachment page, it has a delete link after the browse button of each attachment row, but I have no idea how could this be implemented in my case?

If you add a Button to each composite panel you can call CompositePanel.removeFromParent() to delete itself from the view. If you add a CheckBox in each composite panel and a single delete Button in HATestPanel you first have to find all composite panels (same loop as for your submit button) which are checked for deletion (implement a isChecked() method in CompositePanel) before calling removeFromParent() on them.
