A recipe for Turing-complete logic in reports


The report environment is obviously not the right place to perform complex logic, but when needs must the lack of lambda support in the available JS and troubles getting java 8+ working make a solution desirable. This technique worked for me, and I thought it might be of interest:

    (function () {
       var a = new Object($F{top}.get("buss")); 
       var b = ...;
       for (var p in a) {
       return ...;

Notice the use of a "for" loop and temporary "var"s! This works because the "()" around the "function () {}" turns the declaration into an expression, which ".apply()" can run.

Enjoy responsibly...
