Multiple types separated by pipe (|) at @property are not working during auto-complete, only the last member is evaluated by NetBeans. This breaks e.g. Yii2 compatibility, which uses this feature extensively. In contrast, @var works with multiple types.

Test code:

<?php

/**
 * @property T1|T2|T3 $p
 */
class Test
{
    /**
     * @var T1|T2|T3
     */
    public $v;
}

class T1
{
    public $t1;
}

class T2
{
    public $t2;
}

class T3
{
    public $t3;
}

$test = new Test();

// @var
$test->v->[CTRL+SPACE] // shows t1, t2, t3

// @property
$test->p->[CTRL+SPACE] // shows only t3

?>
