Re: tiles:put / in ActionForward.perform()
Hi,
Do you have specify the Tiles plugin in your struts-config (struts1.1)
or the appropriate ComponentActionServlet (Struts1.0.x) ?
More answers intermixed.

Hi again!
I think I have got some progress in the subject. I found the
org.apache.struts.webapp.tiles.template.DynTemplateAction and with that as
model i added a page looking like this:
/layout6/page2.jsp--
% taglib uri=/WEB-INF/struts-tiles.tld prefix=tiles %
tiles:insert beanName=test.page
/tiles:insert
---
beanName attribute is used to specify to get a definition stored as a
bean in a jsp scope. Definitions declared in a config file aren't store
in such scope. They are stored in the definition factory. You should use
tiles:insert definition=aDefinition ...
So now my action looks like this:
--
action
path=/layout6/page
type=layout.BodyChangeAction
forward
name=success
path=/layout6/page2.jsp /
forward
name=error
path=/layout6/error.jsp /
/action
-
I get the following exception:
javax.servlet.ServletException: Error - Tag Insert : No value defined for
bean 'test.page' with property 'null' in scope 'null'.
You got it because no bean can be found under requested name.
I also tried to request.getAttribute(test.page); but it returns null so to
me it seems like request.setAttribute(test.page, defintion); doesn't reach
page2.jsp??
This is consistant with what I have said before. There is no such bean
in the request context.
Other info:
--/layout6/page-defintion-
definition name=/layout6/page page=/layout6/layout.jsp
put name=header value=/layout6/header.jsp/
put name=footer value=/layout6/footer.jsp/
put name=menu value=/layout6/menu.jsp/
put name=body value=/layout6/body1.jsp/
/definition
--Source of my action -
String forward = success;
String path = request.getParameter(body);
// Change nothing
if(path == null || path.equals()){
// do nothing
}else{
// Try to change body-page
ServletContext context = this.getServlet().getServletContext();
ComponentDefinition cd = null;
try{

definition = definition.substring(0, definition.lastIndexOf('.'));
// Create new definition from and existing
cd = new
ComponentDefinition(DefinitionsUtil.getDefinition(definition, request,
context)) ;
// Alter the definition
cd.putAttribute(body, path);
// Put the definition where the page can find it
DefinitionsUtil.setActionDefinition( request, cd) ;
request.setAttribute(test.page, cd);

Re: tiles:put / in ActionForward.perform()
Ok. so far I have got it but I still doesn't get the request into context.
ComponentContext context = ComponentContext.getContext( request );
returns null so I having a hard time to test the
org.apache.struts.webapp.tiles.test.TestActionTileAction class.
What is wrong when ComponentContext.getContext(request) returns null? I
doesn't get any help from the documentation here.

Ok, I haven't read carefully enough your previous mail.
You can create a new definition from a definition read in the factory,
and then instruct current Struts action to use your new definition. More
precisely, the definition associated to the struts forward will be
overloaded by your definition.
The class org.apache.struts.webapp.tiles.test.TestActionTileAction use
in the tiles-documentation/test do that.
Following is an extract from this class. The code get the definition,
copy it, modify the copy, and then put it in the appropriate request

Re: tiles:put / in ActionForward.perform()
The context is the tile context. It is associated to current tile, and
created when you insert the Tile, or forward to a tile. So, it doesn't
exist if your action is called throw the normal Struts way. But, you
don't need the context to get a definition from the factory and put it
in the request scope in order to be used by the struts forward.

Do the tiles definition and the body attribute have the same name? I would
think you would have to pass two parameters - the definition to act on and
the body attribute to replace. Or the definition is constant and only the
body can change. What does your tiles definition file look like?

type=layout.BodyChangeAction
forward
name=success
path=/layout5/page /
/action
/action-mappings
---
http://localhost:8081/layout5/page.do?body=body2.jsp
-
The url will change body in the defintion from body1.jsp to body2.jsp for
this request.
The definition and the action have the same name. If they didn't have the
same name I must send the name of the definition name as an parameter in the
url. I don't know if there is a better way of doing this?

Subject: tiles:put / in ActionForward.perform()
Hi!
I'm trying to expand my tiles with a dynamic body. I want to control
this
body with a simple parameter in the url eg
http://localhost:8081/myPage?body=aTile.jsp . Does anyone have an
example
of
how to do this?
Thanks in advance

Re: tiles:put / in ActionForward.perform()
Hi !
I think the DefinitionDispatcherAction doesn't do what I want to do
Imagine that you have a definition with 2 tiles (left and body)
In the left tile there are a collection of links that will change the
content of body.
If I understands what the DefinitonDispatcherAction does it will change what
defintion to use. What I want to do is to change one tile in the defintion,
much like a frameset where i doesn't change the frameset, only one page in
it. So I want to call the same defintion and alter a tile in that defintion.
Not change the defintion.
The problem with the perform-method I posted is that it change the tile in
the application-scope and I havn't figured out yet how to make the change
isolate into a request only.
Regards
Roland

Hi,
I think there is an action in the Tiles/Struts distribution doing
exactly that ;-)
Check org.apache.struts.tiles.actions.DefinitionDispatcherAction.

The change in the definition lasts only for the request and will not make
any permanent changes.

Re: tiles:put / in ActionForward.perform()
Ok, I haven't read carefully enough your previous mail.
You can create a new definition from a definition read in the factory,
and then instruct current Struts action to use your new definition. More
precisely, the definition associated to the struts forward will be
overloaded by your definition.
The class org.apache.struts.webapp.tiles.test.TestActionTileAction use
in the tiles-documentation/test do that.
Following is an extract from this class. The code get the definition,
copy it, modify the copy, and then put it in the appropriate request
attribute. The
// Read definition from factory, but we can create it here.
ComponentDefinition definition = DefinitionsUtil.getDefinition( ... );
definition = new ComponentDefinition(definition);
definition.putAttribute( attributeName, aValue );
DefinitionsUtil.setActionDefinition( request, definition);
...
return (mapping.findForward(success));
