random color by "iteration" attrib

[JJ FX]

Hi,

So inside for-each-loop in a wrangle i want to set the color, but this does not work, generates zero values:

@temp = detail("../foreach_begin1_metadata1", "iteration", 0);
@Cd = rand(@temp);

Looks like I dont know how to get the iteration detail attrib. tried in different ways but always gets zeros.

Easiest way is to plug metadata into the wrangle and access it by input number:

int i = detail(1, "iteration");

You can also use full node path like "op:/obj/geo1/foreach_begin1_metadata1" (injecting expression: "op:`opfullpath("../foreach_begin1_metadata1")`"). Or use "opinput:1" string or s@OpInput2 (they numerated from 1 there) string variable.

Unfortunately, other strings will be treated as file paths. "../foreach_begin1_metadata1" will search for file called "foreach_begin1_metadata1" somewhere in $HIP's parent directory.
