With Velocity, this is a simple matter of creating macros to do your work for you. I use macros to generate my <select>'s from a database. Further, you can either place your macros in the file being rendered, or in the velocity global macro file.
So, in the global macro file you define:
#macro names($list) #foreach ($p in $list) $p.name #end #end
Then, in your page, you simply write:
$names($model.projects)
In the macro above, Velocity doesn't care what type 'p' is, as it treats it as an Object any way; it will introspect for an accessor for the 'name' property and render it to the output.

Hello,
This is not entirely maverick specific but I am trying to find a solution to this in maverick environment hence the question.
I am currently using jstl as a view technology but if this can be achieved with velocity and not with jstl then I am quite ready to switch. Prefer to find a quick jstl solution though.
I would like to make my views more modular and reuse common components as much as possible. For example if I iterate over some sort of collection I would rather include a component that knows how to render this object instead of having similar rendering code in so many places.
So instead of this: <c:forEach items="${model.projects}" var="p"> <c:out value="${p.name}"/>, etc. </c:forEach>
I would like to have something like this: (does not work like this though)
<c:forEach items="${model.projects}" var="p">
<c:import url="/components/output-project.jsp">
<c:param name="project" value="${p}"/>
</c:import>
</c:forEach>
and something like this in output-project.jsp: <c:out value="${param.project.name}"/>, etc.
This kind of approach works as far as I only pass simpe strings but not with beans, etc. I need beans :)
So please tell me how do you do this?
best regards, Taavi
