Hi,
There is an example on how to retrieve the tile context in org.apache.struts.webapp.tiles.test.TestActionTileAction.
A tile context is created each time a tile is inserted. The tile context is hold in a ComponentContext object.
Hope this help,
Cedric

tiles context? How do I get that?
The logon.jsp has a struts html:form attribute that is associated to the action class.

with the following tiles-def, I can forward to layout.main and everything is fine:It is not recommended to change a definition dynamically, unless you know very well what you do. A definition content is shared by all the website. Changing the content will be reflected to all user of the definition. If you want to change a definition attribute for the current tiles, you should do so in the tile context, which hold a temporary copy of the definition.
definition name="layout.main" path="/layoutMain.jsp"> <put name="header" value="header.jsp" /> <put name="app" value="layout.app" /> <put name="footer" value="footer.jsp" /> </definition>
<definition name="layout.app" path="/layoutApp.jsp"> <put name="mainMenu" value="menu.main" /> <put name="subMenu" value="subMenu.jsp" /> <put name="body" value="welcome.jsp" /> </definition>
<!-- Menu bar definition --> <definition name="menu.main" path="/menu.jsp" > <putList name="items" > <add value="Item 1" /> <add value="Item 2" /> <add value="Item 3" /> </putList> </definition>
I then modify the tiles-def so that in layout.main app = "logon.jsp" where logon.jsp submit is associated with a struts action. In the struts action I set the layout.main app = "layout.app"
ComponentDefinition layout = TilesUtil.getDefinition("layout.main", request, this.servlet.getServletContext()); layout.put("app", "layout.app");
and forward to "layout.main". So basically after the action everything should be the same as my original setup. However, I get the following error on the forwardThe layout.app name has been interpreted as an URL. It appear that the Tiles mechanism hasn't catch it.
<Jun 20, 2003 1:16:00 PM EDT> <Error> <HTTP> <Included resource or file "/netl-c ommons/layout.app" not found from requested resource "/netl-commons/layoutMain.j sp".>
I don't see how you call the action from the logon.jsp page.

layoutMain.jsp is not changed during my update and looks like
<TABLE border="1"> <TR><TD COLSPAN="2"><tiles:insert attribute="header"/></TD></TR> <TR><TD COLSPAN="2"><tiles:insert attribute="app" /> </TD></TR> <TR><TD COLSPAN="2"><tiles:insert attribute="footer"/></TD></TR> </TABLE>
Any idea why layoutMain.jsp could load layout.app in the original, but can't when I programatically put it into layout.main? I noticed that the put method doesn't have type as an argument for specifying "string", "page", "definition", so I hope that isn't it.
