Hi David,

I added the homeTab binding to WOHyperlink bind it to a String.
Now you lost me. Why did you do that? What are you trying to
achieve?
Trying to set the cssClass programmatically based on whether
homeTab == currentTab or not
Think top down not bottom up.
homeTab always resolves to null so the isOnTab() method always
resolves to false.
OK, let me try to understand this. You have something like this
in your WOD?
SomeLink: WOHyperlink {
action = something;
class = cssClass;
homeTab = "Inventory";
}
Yes that is exactly it.
Is that right? This is going to produce this html:
<a href="...." class="subnav" homeTab = "Inventory">...</a>
It is NOT going to set homeTab on the parent class to "Inventory"
if that is what you were thinking.
You are correct. This is why I was trying to have a generic wrapper
for the link to include the "hometab" information there. But that
doesn't work either ;-)
Nope. Binding synch goes down, not up. It is used to migrate parent
values into the children and then child updates to that value back
into the parent at the end of the RR phase. Just like in real life,
children don't tell their parents.
Or am I totally off track?
You have understood me perfectly. That what I want to do is nuts,
is another thing altogether!
:-) I don't have any quick fix. What I can tell you is that your
design is upside down. You tell WOHyperlinks what to do, they don't
tell you. You need to keep the menu structure and context at a
higher level and push the relevant contextual information down to the
hyperlinks which will render it in HTML.
