bean access in tile def?

[Justin Chin <jc...@nyc.saic.com>]

Folks,

 

I have a message in a jsp which require a dynamic attribute that I set
on a bean from an action class.  I want to use that bean within the
tiles definition file.  Is that possible?  So for example, this is what
I would do in my jsp to get the dynamic attribute:

 

 

<%

int requiredNum =
((com.my.bean.TestBean)session.getAttribute("testbean")).getRequiredcoun
t();

%>

 

<bean:message key="my.message" arg0="<%=requiredNum%>"/>

 

 

My tile def looks like this:

 

  <!-- Layout -->

  <definition name="main.layout" path="/pages/layout/layout.jsp">

     <put name="title"        value=" "/>

     <put name="header"       value="/pages/layout/header.jsp"/>

     <put name="body"         value=""/>

     <put name="directions"   value=""/>

     <put name="footer"       value="/pages/layout/footer.jsp" />

  </definition>

 

 

I want to set "directions" dynamically from a bean which I stuff into
the session.  Is that possible, or am I totally off here?

 

Thanks,

Justin

No, it's not possible. Anyway, are you sure that you want to put a bean 
as a definition attribute? What I mean is that probably you only need to 
extend your base definition with specific ones, overriding the 
"directions" attribute. This is the case when you know all of those 
"directions" attributes at "compile" time.
Otherwise, you can do this in a JSP page:

<tiles:insert definition="main.layout">
    <tiles:put name="directions" beanName="myBean" beanScope="session" />
</tiles:insert>

Anyway I think that support for "beanName", "beanScope", etc. attributes 
in Tiles definitions should be provided.

Justin,

I've been working on a similar problem, and based on what I've seen
posted here, I don't think it is doable (using definitions).

Technically, it seems that in order for what you'd like to do to work,
the definitions factory would need to be able to see the scope you're
placing that variable in - but since it's just a configuration file (and
hence isn't parsed/has no scope), it can't.

Hopefully I'm wrong (both for your sake and mine), but that's the
explanation I was given when I asked a similar question.

What's always got me about this issue is that the following:

Use and Set Bean in configuration file
It is now possible to use and set beans in the configuration file. Such
bean can then be set as a <put> or <putList> tag value.
This increase and facilitate menu creation.

what this is in reference to?
