Hi All.
This is probably something obvious (or obviously wrong way of doing
it).
I have my Main page, a user logs in and stuff changes on that
page. The user navigates to another page, something gets done
there and I return to the Main page with "return pageWithName()".
Problem is that "return pageWithName()" creates another instance of
the Main page. I need my previously instantiated page.
I get the context ID of the Main page using
this.context().contextID() before I go to the second page.
Then I tried this when I finish with the second page:
return
session().restorePageForContextID(returnToPageWithThisContext);
This returns null, going back to the second page.
How do I get my previously instantiated Main page back? (there is
no browser back link, I need to do this in the code)
Thanks for any ideas (or the 'duh' solution).
This is what do in the class that I use for the super class for
pages that need to go back:
public abstract class PageWithPreviousPage extends WOComponent {
private WOComponent previousPage;
public PageWithPreviousPage(WOContext context) {
super(context);
previousPage = context.page();
}
public WOComponent previousPage() {
previousPage._awakeInContext(context());
return previousPage;
}
Then you can just say return previousPage() to go back
I'll have to try this. Since I have a number of pages that do this it
may be the way to go.
Thanks!
