Apache Velocity - Parse VM file Based Upon Total Foreach Count

I am trying to create an Apache Velocity Script that executes a VM file based upon a foreach count of 1 or 2 respectively.

Here is the code that I am using:

#set ($i = 0)
#foreach ($report in $reportInfo.reportList)
#set ($i = $i + 1)
#if ($i == 2)
#parse ("/MyReport/Report1.vm")
#end
#end

#set ($j = 0)
#foreach ($Report in $reportInfo.reportlist)
#set ($j = $j + 1)
#if ($j == 1 )
#parse ("/MyReport/Report2.vm")
#end
#end

What ends up happening is that if there is a foreach total of 2, it will also run Report2.vm since the count is "1 2". Is there anyway that I can code this to look at either the sum, max, or total of the count for my variables?

Sounds to me like you just want to perform some logic based off the size of the list. 

#if ($reportInfo.reportList.size() == 1)
#parse ("/MyReport/Report2.vm")
#elseif ($reportInfo.reportList.size() == 2)
#parse ("/MyReport/Report1.vm")
#end

Hi I understand that you would like to count how many times your 'for-each' loop has been executing, apache velocity templating engine provides an easy way to get the loop counter so that you can do something like the following:

<table>
#foreach( $customer in $customerList )
<tr><td>$foreach.count</td><td>$customer.Name</td></tr>
#end
</table>

Velocity also has other convenience counters like:
1. $foreach.index instead of $foreach.count
2. $foreach.hasNext
3. $foreach.first and $foreach.last are also provided to compliment $foreach.hasNext

Please refer Apache Velocity user guide for more examples.
