Thanks. I got the attributes form the Tiles Context but only on the JSP that
had a <tiles:insert>. Can I somehow make the Tiles Definition session
scoped? Also in case of nested Tiles, will there be multiple Tile Contexts?

Definitions declared in the configuration file belong to the definition factory which is in the application scope. You can create yourself and store definitions in any jsp scope like a regular java bean. You insert it with <tiles:insert name="defName" scope="page|request|session|application" />.
In the case of nested tiles, there is one different context for each nested tiles.

Hi,

Where is declared your action ? To be able to retrieve the tiles
context, there should be a tiles context. There is a tiles context only
if you insert an Tiles, or do a forward from an action to a definition.
In this later case, the context is created after the action.

I want to modify the Attributes in a tiles Definition from my Action
classes. Is this possible? I have tried the following code inside the

Action

class but do not get an Attribute against the name, instead I get a null.

ComponentContext context = ComponentContext.getContext(request);
java.util.List list =

(java.util.List)context.getAttribute("tabList");

Is it because it is request scoped? Can i make it session-scoped? Also I

get

an empty iterator when I try to traverse the list of attributes in the

Tiles

Context.

Iterator iter = context.getAttributeNames();
System.out.println(iter.next())
System.out.print("Printing Attrbutes:");
while(iter.hasNext())
{
System.out.println("Attribute"+ ((String)iter.next()));
}

My tiles definition is given below. Thanks a lot.

Subject: Nested layouts (Panels inside Tabs)

I have a Tabs Layout setup and inside a tab I have another layout with

two

panels(menu and content). This is my definition:

<definition name="index.page" path="/webpages/layouts/tabsLayout.jsp" >
<put name="header" value="/webpages/header.jsp"/>
<put name="footer" value="/webpages/footer.jsp" />dfs
<put name="selectedIndex" value="0" />s
<put name="parameterName" value="selected" />
<putList name="tabList" >
<item value="Home" link="/webpages/home.jsp"
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" />
<item value="Template" link="/webpages/template.jsp"
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" />
<item value="Search" link="/webpages/search.jsp"
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" />
</putList>
</definition>

The link to "Template" i.e the template.jsp file follows a simple

layout:

<definition name="templateview.default" path="/webpages/layout.jsp">
<put name="menu" value="/webpages/tiles/categoryTile.jsp"/>
<put name="body" value="/webpages/tiles/templateTile.jsp"/>
</definition>

The problem is that when I click on any link inside one of the panels in
templateTile.jsp or any other file, it breaks out of the Tabular layout

and

displays it as just two panels. This problem can be reproduced if you

run

the tiles-documentation example and go to
http://localhost:8080/tiles-documentation/examples/tabs.jsp. Now here if

you

click on any link in the menu the page will open outside the tab layout.

The hyperlinks in my "Menu" panel point to Action classes. I am

forwarding

requests from the Action classes to Tiles Definitions.

What should I do to tackle this problem?

Also can anyone guide me to a resource for Nested Tabs?

Thanks for your time.
