Hi James and Firas,
Yes I'm seeing a little light now :)
1) How does getting components from a different page affect the
render/rewind cycle of the current page?
2) What if the Block that comes from another page has some ognl bindings.
How do those get resolved, as I'm now on an entirely different page?
3) What are the best use-cases for such usage?
Thanks, Karthik

Hi,
There's IMO an easier way.
Assume
HtmlBlocks - the page containing the external block(s)
ClientPage - the page that uses those external blocks
In your ClientPage.page you write:
<inject property="exBlocks" type="page" object="HtmlBlocks" />
And to access these blocks you write:
ognl:exBlocks.components.theNameOfTheBlock
Hope this helps,
</Firas>

Subject: Re: Question regarding Block/RenderBlock
You can create a page that has a bunch of @Blocks in it and you can use
those blocks in other pages. We do that in Trails and it works quite
nicely. Check out the org.apache.tapestry.util.ComponentAddress
class. It allows you to "look up" components on other pages. So, you can
use it this way...
public Block getReusableBlockFromAnotherPage() {
ComponentAddress addr = new ComponentAddress( "MyReusableBlocksPage",
"myReusableBlock" );
return ( Block )addr.findComponent(getRequestCycle());
}
In your page, you'd do this:
<span jwcid="@RenderBlock" block="ognl:reusableBlockFromAnotherPage" />
This is off the top of my head, so the syntax might not be exactly
correct,
but you get the general idea I hope. Hope that helps!
