Re: Looping over a List

What you have already should work, you're just going out of bounds by not checking if fixtures_index + 1 is still less than fixtures?size.

You can also use the range .. operator.  There is also the fixture_has_next loop variable you could use to check the bounds.  Lots of different ways to do this really..

Here's one (untested):
[#assign fixtures = resource.fixtures /]
[#assign n = fixtures?size - 1 /]
[#list 0..n as i]
	[#assign fixture = fixtures[i] /]
	[#if i == 0 || previousFixture.competition.name.abbrTextLong != fixture.competition.name.abbrTextLong]
		<div class="compName">${fixture.competition.name.abbrTextLong}</div>
	[/#if]
	[#assign previousFixture = fixture /]
[/#list]

Subject: [FreeMarker-user] Looping over a List


Hello,

Is it possible to use the item_index value to retrieve a specific value from
a list. eg)

<#list resource.fixtures as fixtures>				
	<#if fixtures[fixtures_index+1].competition.name.abbrTextLong !=
fixtures[fixtures_index].competition.name.abbrTextLong >
		<div class="compName">${fixtures.competition.name.abbrTextLong}</div>	
	</#if>
</#list>

The above does not work, fixtures is a standard java ArrayList.

Basically what I am trying to do is compare some properties on the next
value in the list with the current value and if they aren't the same i wan't
to display a header.

It seems like #list is more like a  for each loop and there doesn't seem an
obvious way to do this?

Thanks
Jonathan
