I'm starting with a list of IQNs entered in CSV format from an input variable, iqnList, to create multiple igroups based on the server name
Example is: iqn.1994-05.com.redhat:john, iqn.1994-05.com.redhat:joe, iqn.1994-05.com.redhat:bob
I created a function, getServerFromIQN that takes the iqn name and just leaves the host name.
I create a row loop for Number of Time with Number of Times equal to getSize($iqnList)
The Variable Index is set to iGroupIdx
Variable Name is iGroupName
Initial Value is getServerFromIQN(getValueAt($iqnList,1))
Expression is getServerFromIQN(getValueAt($iqnList,iGroupIdx+1))
My problem is that if the the Expression is performed after the last item in my list and so there isn't an iGroupIdx+1 to look at and I get an error.
How can I set the Expression to only evaluate if the size of the list is less than the iGroupIdx? I tried an if/then, but got an error evaluating the expression.
This is WFA 2.2.
Solved! See The Solution
When I remove the +1, I don't get an error, but it loops through the first item twice. I'm doing a NoOp to see if the igroup exists before creating it and end up with incorrect results when I remove the +1.
I think I need the expression, to not calculate on the last iteration.
I've attached the dar file to help out.
