T5.1: get the current page context from a component
Hi,
Is there a way to get the page context from a subcomponent? Right now
I pass it as a component parameter, but that looks ugly.
Regards, Sergey.

Well, actually what I need is
- dedicated activation context for a component, something like current
onActivate() for pages
- passing request parameters to PageLink, like <t:PageLink
requestparameters="linkRequestParamaters" context="linkContext" >
I'm implementing a pager that generates "forward" - "backward" links
without EventLinks to avoid excessive http requests.
The first item would help me to avoid reflection.
And the second would help me to code optional "pageNum" parameter
using the standard request parameter notation "?pageNum=3", not my own
odd format "/pageNum-3:anotherParameter-ENUM_PARAMATER_VALUE" that I
implemented by contributing ParamaterMap ValueEncoder as was advised
on this list for optional parameters.

Yes. But we can try to find a bfile a JIRA for a better way of getting
that info without using reflection.

The magic of Tapestry modifying our component classes in runtime . . .

And call onPassivate() through reflection, right?
I missed this case because did not expect my "live" page to extend
interface Component that is returned from componentResources.getPage()
Thanks for your answers!

@Inject ComponentResources and then call its getPage() method. You may
need to cast the returned object.

Well, how I can inject not just ConcretePage but the current page? So
the component can be reused on different pages.

Using "inherit" binding also means parameter declaration as I
understand from a very brief documentation.

Calling onPassivate() directly? ;)

Never tried it, but isn't the inherited: binding what you are looking for?
You could also inject the container into the component, and then
reference your context somehow directly.
