IExternalPage
Hi,
All my pages are implementing the IExternalPage interface as I decided that
all my pages will be accessed via the ExternalLink component, but, how do I
implement the activation of a page inside my application code:
public void onCancel(IRequestCycle cycle) {
ViewProfile page = (ViewProfile) cycle.getPage("ViewProfile");
cycle.activate(page);
}
The ViewProfile needs date loaded in the activateExternalPage method. Shall
I move the code to a common method? Or is there a way to activate the
external link?
Thanks.
David

Alternatively, if you would prefer to "tell your pages" what their
properties are, rather than have them "discover" there properties in
pageRenderListener, then it's as simple as:
public void onCancel(IRequestCycle cycle) {
ViewProfile page = (ViewProfile) cycle.getPage("ViewProfile");
page.setMyProperty(...);
page.setMyProperty2(...);
cycle.activate(page);
}
The two different approaches are thought of as "push" versus "pull".
If you have property setters such as above, then the implementation of
activateExternalPage should use them as well, extracting the values from the
parameters.

You can implement pageBeginRener() of PageRenderListener interface and
put all the work in there. Just set the parameters you need in
activateExternalPage() and let pageBeginRender() handle the rest.
