Re: [rules-users] Functions with array parameters (double[]) cease to compile in 5.2.0
Situation definitely treaky - I am working as author on DroolsTab plugin to
Protege (http://protegewiki.stanford.edu/wiki/DroolsTab). In this project
drl file is generated programmatically and sent through pipe to
PackageBuilder. I did some experiments as you suggested. Results:
1. Only one function in package does not produce error messages
2. Two similar functions produce only one error message "In package
TestExecutor error: [ prevPoint : unable to resolve type while building
function
]
function name: prevPoint" and allways on last function in spite of their
order.
Here is corresponding drl file:

In 5.1.1 all have been compiling well and working great :) :(
