The problems is that you want to read attributes inside non-layout
pages. In your case your layout page is "standard.jsp" and you can read
attributes (i.e. using <tiles:insert attribute....>,
<tiles:useAttribute>, <tiles:importAttribute>) only in that page.
To solve your problem, use <tiles:importAttribute> to import your
attribute in request scope in "standard.jsp":
<tiles:importAttribute name="pgList" scope="request">
Then use it as a normal request-scoped bean.
