Velocity accessing collections by index

Question

In the following code I am trying to access a collection with a single member.  The foreach works as described but I am unable to access items in the collection by index.

#set($customFields = $customFieldManager.getCustomFieldObjectsByName("Property"))

$customFields[0].name

#if(!$customFields.empty)
  #foreach($customField in $customFields)
     $customField.name 
  #end
#end

Prints

[Property][0].name

Property

What am I not understanding?

Glad to see you worked it out just about fine.

In my experience this sort of matters can get (no pun intended) a bit tricky ;)

I got this to work by using the .get() method!

#set($customFields = $customFieldManager.getCustomFieldObjectsByName("Property"))

#set($propertyField = $customFields.get(0)) ## Can only be the "Property" field (or bust)

then to get the "property" field value I did this:

$issue.getCustomFieldValue($propertyField.id)

No more loops required!!!

It does return the expected custom field and it does contain the expected value if I use :

$customField.value

Of course this works only in the loop!

If  use:

$customFields[0].value // I tried [1] as well

then that too doesn't work.

So at the moment to access an item in an array I seem forced to use a loop. Which means iterating through the loop until I reach the required index.
