This feature is requested for Komodo IDE as well, here is a test script that can be used to repro the problem:

<?php

class testclass {
static private $name;

static public function show_name() {
    //do something with $name
    self::$name = "Sir John\n" . self::$name;
    return self::$name;
}

}

echo testclass::show_name();

?>

To repro, but a breakpoint at line 9. The value of self::$name is not visible.

Duplicate of 0000623, which is now fixed.
