Here is the link to the documentation on the <bean:size> tag. As you will read, "collection" should only be used if you're using a scriptlet that evaluates to a collection. Use
name to refer to the bean and optionally
property to refer to the getter to be called to retrieve the collection.
So, if you specify name="PositionBean" and property="posisi_list",
Struts will find PositionBean in some scope and call the getPosisi_list() method on it to get the collection.
If you have a collection in a scope with the name "posisi_list",
you should simply specify:
<bean:size id="pb_list" name="posisi_list" />
