[jira] [Created] (OFBIZ-4379) Get first from list tag in screen's and form's action tag.

[Nicolas Malin (Jira)]

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

                 Key: OFBIZ-4379
                 URL: https://issues.apache.org/jira/browse/OFBIZ-4379
             Project: OFBiz
          Issue Type: New Feature
          Components: framework
    Affects Versions: Release 10.04, SVN trunk
            Reporter: Ankit Jain
            Priority: Minor
             Fix For: Release Branch 10.04, SVN trunk


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.

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]"/>

-----------------------------------

Hello David,

I agree with what you say, and yes we can use your suggested way, but this tag is also present in the services, so a point came in my mind why we can't use the same tag in screens and forms. That's why created a patch for it.

HTH :)
