Hello Ricardo;

Any components that you put into the WOSwitchComponent behave stateless. You can't depend on the same instance being returned to you on the next request-response cycle. In all of my projects I do a similar thing to what you are doing, but I have developed a navigation system around this to store state, "do breadcrumbs" etc... etc... this system works very well for me. You can find out more about this infrastructure by downloading LEWOStuff from my website (www.lindesay.co.nz) and reading the overview PDF.

cheers.

I have a little app with a single page Main.wo.  :-)

This page (Main.wo) provides the look of all pages.  The only thing
that changes is the content in that page.  So I have a
WOSwitchComponent declared in my Main.wod as follows:

ContentComponent: WOSwitchComponent { WOComponentName =
contentComponentName; }

Ok... Now of on my content components has a little bit of javascript
(ajax) code.  For example, something is selected in a pop-up a direct
action is sent to the application.  The direct action in my app is
invoked and it reads the direct action url arguments and then
generates an HTML response that is sent back to the browser and it's
loaded into a div.  Works great!

Now, I want to do things differently.   I want to find out if it's
possible for the direct action to get a hold of the current content
component being displayed by Main.wo.  Let's say that the current
content component is called "Foo".    Well, if I do pageWithName
("Foo") it will create a new copy.  What I want is to get a hold of
the existing one, pass in the direct action url arguments and then
return that as the response.
