Re: Customize view based on content --> Tiles?

  Hi,

  Maybe you can use a Struts action that prepare the data, select the 
appropriate view and forward to it. The view can be a Tiles.

What I meant was, you can specify it on an individual tile, as well as the
definition I believe.

You can also associate a controller with a tile definition.

What you need to do is implement org.apache.struts.tiles.Controller for
each separate tile.  You associate a controller with a tile in your
tiles-defs.xml.  The controller gets called before the tile is rendered.

Put the view/business logic for the tile in each tile's controller.

Keep the logic in the action that forwards to separate views in the
action.  When the action forwards to view1, the controller for view1
will be called.  view1 doesn't have to know anything about view2,
Likewise, if you forward to view2, the business logic for view1 never
gets called.

We have many, many tiles and when we discovered controllers we jumped
for joy.

Hope this helps,
