Using components multiple times
I want to use a single conditional statement multiple times in the same
page. When doing this, I get this error:
"Template for component EditLevel contains multiple references to
embedded component isNotNew"
This is true. I have one conditional component specified and I am
trying to use it twice. I could create multiple conditional components
in my .page file, but is this really needed?

I know there was some discussion about adding a conditional to all
components, when that happens this would not be a problem. But for now I
think the component IDs within a container should be unique.

I'm trying to wrap one Conditional element around several pieces of text
in my HTML file without having several copies of the same Conditional
component in my page specification.
Its just a convinience item.
Thanks.

I don't understand what you are trying to do.

Same goes for Links. I am running into situations where I have the
same link at the top and bottom of a page. Seems pretty bogus that
they have to be named differently.
I'd rather see uniqueness enforced by the Form component on it's
children, perhaps controlled by a parameter. Unique IDs should not be
a restriction of components in general.

Yes, this is correct, but I can't imagine having 10 copies of a single
Conditional. I can undertand this for form elements, but I think an
attribute to allow for multiple copies would be great to add to the
Conditional Component.

At the spec level (jwc files) you can use copy-of
<component id="MyCopy" copy-of="originalId"/>
In templates you have to create a new one every time. ( I think)

You can't do that I'm afraid - a shortcoming, as component ids must be
unique within the component/page.
You can either put write out the conditional statement in your HTML
template using @Conditional and the condition parameter, or create a new
component, say @IsNew which just contains the condition, allows and
renders the body ie.
<span jwcid="isNew">
<span jwcid="@RenderBody"/>
</span>
in your IsNew.html template.
In your new IsNew.jwc file you'd do something like:
<component-specification allow-body="yes">
<component id="isNew" type="Condition">
<binding name="condition" expression="your-condition"/>
</component>
</component-specification>
You can then use it in your other components/pages.
It's a bit of a workaround, but can be quite useful.
