Hi everyone,
I have a wizard with a few pages in it and I am trying to dynamically
change the contents of a page based on the inputs of the previous page.
The issue I am having is how do you do this? createControl is only called
once at the beginning of the creation of the wizard, which doesn't help
because it isn't known at that time what the page will look like. In
essence all I want to do is have a textbox on one page allow you to enter
a number and then show that number of textboxes on the next page. Should
be simple, right?
Also, how do you trigger the page's "refresh"? It seems like getNextPage
is called twice per page, once when you enter the page and again when you
leave it.
I have searched all through this forum on dynamically changing wizard
pages but haven't been able to find a working example. If anyone has an
example that would be great!
Thanks,
Andy

Yes, I think that you have to do a .layout(true) on your parent composite.
