tml if statements: unique id components
Hi!
I have in some of my .tml pages several IF statements, which should show
some - depending on the if clause - actionlinks.
if A
actionlink 1
actionlink 2
if B
actionlink 1
now, tapestry throws an exception, because i was giving the actionlink 1 the
id 1 which then was occuring 2 times in my tml code. I could fix it with
giving it another id (1a, 1b) but had also then to add onActionFromId1 and
onActionFromId2 -> which BOTH are doing the same.
Is there some better way to reuse the same actionlink on my page within IF
statements or is this more a HTML issue / which, at the end, says in generel
that no ID should be reused (ID / as a unique identifier)
thx

This is the exact reason for the EventLink component.

Or try the EventLink. Multiple EventLinks can share the same handler
method.

You can also avoid the if component all together using this pattern:

Declare your shared content in a <t:block id="foo">...</t:block>
Then use <t:delegate to="foo" /> when you want to include the "foo" block in
your logic.
