TOPS/PDG array attributes in expressions

[Conor.la]

Hi,

OK my scene is roughly a PDG setup with some work items,  those  have all been merged together into a single work item where all the attributes are merged into arrays. 

I am looking to access those attributes using component syntax ( @pdgoutput.1 or @pdgoutput.2 ).  This works when I manually type in the component pull.  I cannot get this to work in a For Number loop using the iter count.

How can I build an expression that uses the string of the first part of the attribute ( "@pdgoutput." )  and concatenates it together with an detail interger in a SOP loop like @iteration?

I have tried such expressions

@pdgoutput.`detail("/obj/geo/merge1","iteration",0)`

or even

strcat("@pdgoutput.",`detail("/obj/geo/merge1","iteration",0)`)

Though these all resolve to 0

I have thought to also try something like atof() though that wasn't working for me either.  

 

Does anyone know how to work up pdg array attributes in an expression like this? 
Is there a better way to do this?

This seemed to work; I had a tops @foo attribute array with 1,2,3,4, and in a for loop i could accees it and get the index with

evals("@foo."+detail(-1,'iteration',0))

Where the metadata node was wired in as a spare input.

This worked!  Thank you!
