I have implemented something like this. I have a link to my page, e.g.
index.jsp, with a view parameter. If view=paged, then the pagesize
attribute is set to my desired page size. If view=all, the pagesize is set
to the size of the list (but the pagesize="0" tip from Ed is cool, I didn't
know that). If view isn't specified, then you can do whichever way you want
to be the default.
So the page looks something like:
<%-- Calculate the pagesize based on the view value. --%>
<%-- This uses 10 as the default if view is paged or --%>
<%-- view is not specified. If view is all, the size --%>
<%-- is calculated from the list size. --%>
<c:choose>
<c:when test="${param.view == 'all'}">
<c:set var="pagesize" value="${fn:length(list)}"/>
</c:when>
<c:otherwise>
<c:set var="pagesize" value="10"/>
</c:otherwise>
</c:choose>
<%-- Display table --%>
<display:table ... pagesize="${pagesize}">
...
</display:table>
<%-- Pick which paging link to show. If all is --%>
<%-- is specified, show paged, and vice versa. --%>
<c:choose>
<c:when test="${param.view == 'all'}">
<a href="index.jsp?view=paged>View Paged</a>
</c:when>
<c:otherwise>
<a href="index.jsp?view=all>View All</a>
</c:otherwise>
</c:choose>
Again, in that top block, you should be able to discard the fn:length() and
just specify 0, but I haven't done that myself.
