The first tags says if A.B is not null rather than if A && B are not
null.
You may need to use more nesting, maybe something like
<logic:present name="A">
<logic:present name="A" property="B">
<logic:present name="A" property="B.property">
some jsp/html
</logic:present>
</logic:present>
</logic:present>
