#4 Notice in saja.php

[Anonymous]

The are two more notice at 229 and 230

It is not always true that there are action and property.

list($target, $action) = $this->texplode(',', $target);
list($targetId, $targetProperty) = $this->texplode(':', $target);

It is sufficient to correct as follow:
@list($target, $action) = $this->texplode(',', $target);
@list($targetId, $targetProperty) = $this->texplode(':', $target);
