Hello,
I am trying to get a navigation bar to work so that an image changes
when the user is on the page (like the tabs on Apple's site).
The way I have set it up is to have a page wrapper containing a
WOComponentContent and a NavigationBar Component made up of Rollover
components. In my API for the wrapper I have set a boolean variable
called "tabOne" and for all of the components that fill the
"WOComponentContent" under "tabOne" I have set their "tabOne" binding
to "true".
I have also placed "tabOne" variables in the wrapper component, the
NavigationBar component and the Rollover component. I have wrapped the
rollover button for tabOne in a conditional to display the rollover
when the boolean is false (i.e. not on a page that is in tabOne) and a
static image when the boolean is true. My problem is that the boolean
is always evaluating to false on pages where "tabOne" is true and as a
result only the rollover is displayed in its conditional. From my
reading, it seems that the component communication is automatic from
the parent components to child components so long as the variables are
named the same thing.
Am I misunderstanding something about how the communication would occur
from ComponentContent>Wrapper>NavigationBar>Rollover ? If so, what
would be a better way to implement this? Thanks,
David
