David E. Jones commented on OFBIZ-4379:
---------------------------------------

Why not just use the [] syntax to get the first element? In other words, something like:

<set field="websiteContent" from-field="websiteContentList[0]"/>

> Get first from list tag in screen's and form's action tag.

> In most of the cases we need to get first record from a list in screen and form widgets then we have to do something like this: 
> for eg:
> <set field="websiteContent" value="${groovy: org.ofbiz.entity.util.EntityUtil.getFirst(websiteContentList);}"/>
> Instead of using like this my idea is to add a tag like <first-from-list/> in Screen & Form widget's action tag, so one can easily get first record from a list.
