Replicate several arrays with apply()

Hi,

I want to replicate several arrays with the apply() function any idea how to do it with a rule.

I am using now this expression rule:

= load(
/* ri!data is List of Text String, ri!fieldCount is Integer */
local!count: count(ri!data)/ri!fieldCount,

apply(
type!ParseTest(_,_,_),
merge(
index(ri!data, 1+ri!fieldCount*enumerate(local!count), null),
index(ri!data, 2+ri!fieldCount*enumerate(local!count), null),
index(ri!data, 3+ri!fieldCount*enumerate(local!count), null))
)
)

And i want to replicate the part: index(ri!data, 1+ri!fieldCount*enumerate(local!count), null)

I tried this:

= load(
/* ri!data is List of Text String, ri!fieldCount is Integer */
local!count: count(ri!data)/ri!fieldCount,
local!numListFields: 1+enumerate(ri!fieldCount),
apply(
'type!{urn:com:appian:types}ParseTest'(_,_,_),
apply(rule!arraysForCDTPopulate(ri!data,ri!fieldCount,local!count,_),local!numListFields)
)
)

Where the rule!arraysForCDTPopulate(ri!data,ri!fieldCount,ri!count,ri!numListFields) is like this:

index(ri!data, ri!numListFields+ri!fieldCount*enumerate(ri!count),null)

But this is retrieving the that all in 1 array and i need the data separated in 3 arrays so the 'type!{urn:com:appian:types}ParseTest'(_,_,_) works.

Any suggestion?
