TreeViewer and Wizard Page [message #439522]

Hi all,
I have a TreeViewer on a WizardPage to display a list of countries. On the
next page I display all the states in all the countries using a
CheckBoxTreeViewer. I am adding up relevant objects in getInitialInput()
method of the individual page. Everything is static here.
Now I want that user should select one country on the first page and on
the next page, states only from the selected country be displayed.

I am handling country selection but I have no idea how to populate objects
in the next page after my selection on the first page. And even if I add
the required objects, how do I tell the next wizard page to display the
elements I added right now ? Basically how do I call the getInitialInput()
method of the second page only after my selection on the first page ? Do
we have any method of populating the checkbox tree based on conditions
with respect to Wizard Page?

getInitialInput() method is my method where I return root object as an
argument to the setInput() method of StructuredViewer -this way:
viewer.setInput(getInitialInput());

Thanks
