Product Version: NetBeans IDE 7.0.1 (Build 201107282000)
Java: 1.6.0_25; Java HotSpot(TM) Client VM 20.0-b11
System: Windows XP version 5.1 running on x86; Cp1252; en_NZ (nb)
C++ plugin: Version 1.14.2.1
Compiler: MinGW g++ 4.6.1

In a Netbeans C++ project, if I write:

#include <iostream>
#include <vector>
#include <algorithm>
int main()
{
    std::vector<int> container = {1,2,3,4};
    std::for_each(container.begin(),container.end(),
        [] (int x) {std::cout << "\"" << x << "\"\n";});
}

the editor highlights all occurances of x in the line with the lambda and says "unable to resolve identifier x" even though the program compiles and runs with no problem.

So the syntax highlighting of lambda parameters doesn't seem to be correct.
It's a low priority because the code compiles and runs fine.
