is there something similar to c:forEach in JSF

[Khopkar Amarish]

Hi Guys,

is there a way to retrieve indexed properties in JSF inside of a loop like structure like c:forEach or logic:iterate so that you can use indexed properties for the h: tags in JSF like #{myBean.property[counter]}

I can't seem to find a way to do this easily

Not really. What are you trying to do exactly and maybe we can find a better alternative for you.

Hi,

I've looked for this in a lot of places and can't seem to find a solution. I'm trying to do a form with a table that has a dynamic number of rows each with an input radio and input text field which are indexed properties.

Unfortunately I'm on JSP 2.0 and don't currently have the option to switch to 2.1 and upgrade my EL version.

My question is how do you do a for loop or a c:forEach so that these input fields with have a value attribute that is either:

1. indexed like value="#{myBean.values[index].type}"

OR as part of a Collection like

2. c:forEach var='nxt' items='#{myBean.values}'
and then value='#{nxt.type}'

or something to that effect?

Any insight would be greatly appreciated.

Why do you need to do this? A dataTable already loops through your collection for you.

I'm actually trying to render a table with a dynamic collection of rows having input fields (each row in the collection has a text and radio button). Ideally, I would map the text fields and radio buttons in this collection to item objects in Collections in my bean.

Is a data table the best way to do this?

Yes! A dataTable is for rendering a table based on come collection. Or collection of collections.
