[T5] dont understand behaivior onActivate/onPrepareFromEditForm
senario:
a page contains al link like this
@Component(parameters = {"page=IssueEdit", "context=list:project.id, 0, 0"})
private PageLink _issueEditLink;
the IssueEdit page contains following methods
public void onActivate(long ticketId)
{
if (getLogger().isInfoEnabled())
getLogger().info("onActivate-ticketId");
}
public void onActivate(long projectId, long componentId, long ticketId)
{
if (getLogger().isInfoEnabled())
getLogger().info("onActivate-ticketId-componentId-projectId");
}
@Override
protected void onPrepareFromEditForm()
{
if (getLogger().isInfoEnabled())
getLogger().info("onPrepareFromEditForm from page class");
// call from super class AbstractBasePage
super.onPrepareFromEditForm();
}
and thats the logging output if i click the link described above;
2008-02-26 10:59:14,534 INFO pages.IssueEdit -
onActivate-ticketId-componentId-projectId
2008-02-26 10:59:14,534 INFO pages.IssueEdit - onActivate-ticketId
2008-02-26 10:59:14,706 INFO pages.IssueEdit - onPrepareFromEditForm from

There are documented rules about order of method invocation with
respect to event handler methods. Basically, don't call super();
Tapestry will be invoking super-class event handler methods for you.
I tend to make event handler methods on base classes final to remove
any ambiguity.

Hi Sven,
It's too much trouble to parse your message and try to figure out what your
question is. To get a helpful answer you should ask a clear and specific
question like "Why does X come after Y" or "Why is X called".
On a side note, the pattern of calling getLogger().isInfoEnabled() is
generally used to avoid the extra cost of building the message being logged
(concatenating many strings for instance). You aren't building a message so
you are essentially just adding noise to your source since the info method
only outputs your string if info is enabled.
