I have a Struts 2 Form from which I am entering fields including Email IDs.Now user can have click on add to dynamically add new text box for entering more email Ids. So the names of textboxes in such a case would be created on user click of add more button. But the problem is that field names in Struts 2 have to be properties of Action class with setter getter methods. But how can i create property and setter getter for a textbox whose name is not yet known. ? Suppose there are 5 fields as text box and I have 5 properties in action class with setter getter.Now I click add button and dynamically generate a new text box for additional emailId.How can i have this name as property of action class when this name is known only dynamically on click of add button?

thanks

Use an indexed property (yes, that page is for Struts 1.x, but the principal applies in Struts 2.x). Basically the getter/setter on your action or data object should take a collection and the name of your text box should be the collection name plus an index.

Thanks.Apart from that I read one more post:
webpage

In this I saw the idea that create dynamic text box create them as textBox1,textBox2 and so on and use the same name in FormBean( in Action Class only in struts 2).

I tried the below:

Idea is to use same name in Action Class property.
The above works but below does not:

Now I would use the name EmailId1 as property but the above does not work.Please advice.

Thanks.

Are you looking at this example? Notice that your code does not look like the code in the example.
You also haven't shown your action. I assume your getter and setter takes a collection.

Please do not post the same question more than once. I've already linked to a relevant example in your other post. Since you found Monica's post you can obviously search the forum for other examples, of which there are many. We will not do your work for you. If you show some effort we would be glad to help you.
