Re: Dynamically populating tile lists at runtime for menus - Is it possible?

[Jason Lea]

The docs show that <item> doesn't accept a role attribute, and the <add> 
tag does but not in a definiton so I don't think you can.

I have a menu  tile that is displayed on every page.

I use the <logic:present> to check user roles, and display items 
depending on that.

<logic:present role="admin">
  <span class="menuitem"><html:link forward="admin" 
titleKey="admin.title"><bean:message key="admin.menu" /></html:link></span>
</logic:present>

<logic:present role="a_user">
  ...
</logic:present>
... (general links that any user can access, don't have to be logged in)

Your other option might be to use a tile controller to generate the list.

Hi,

I am in the process of building a Struts/Tiles application that needs to be
able to dynamically construct menu lists when the user logs in.
For instance a user may belong to the base user role, therefore a single
tab should be displayed but he could also belong to an admin role,
therefore 2 tabs need to be displayed.
Is there a way of building the

  <putList name="tabList">
      <item value="Doc Home" link="/index.jsp" />
      .
      .
      .
      .
      .
</putList>
dynamically?

All the documentation I have found so far seems to suggest that all these
lists need to be predefined, however I want to be able to retrieve the
item's from a database within a Struts action as the number of combinations
of  list items could run into the hundreds.
