It is known that the iteration depth of variables is limited in
Cfengine. As of 3.0.4p2 the following test.cf
body common control
{
bundlesequence => { "outer", "inner" };
}
bundle agent outer
{
vars:
"arr[idx1]" string => "this is an array element";
"arr[idx2]" slist => { "This", "is", "an", "array", "element", "too" };
"choice" string => "idx2";
reports:
Yr2010::
"outer: $(arr[$(choice)])";
}
bundle agent inner
{
vars:
"idx" slist => getindices("outer.arr");
reports:
Yr2010::
"inner: $(outer.arr[$(idx)])";
}
produced the following output:
R: outer: This
R: outer: is
R: outer: an
R: outer: array
R: outer: element
R: outer: too
R: inner: this is an array element
R: inner: $(outer.arr[idx2])
and 3.0.4 wasn't even capable to iterate over an slist in an array in
the outer bundle, so you're using some version earlier than 3.0.4p2, I
guess.
