T5: onActivate() called twice
Hi,
I noticed that my onActivate() is called twice.
I solved the problem by changing onActivate() into onActivate(Object[]
parameters).
Now it is only called once. But is this the way to do this or is there a
better way?
greetings,
Leon

Hi Leon,
I am facing the same problem with the onActivate() method calling twice.
Did you find any solution for this?
Thanks,
Yees.

Hi Davor,
Indeed, I have a BasePage that implements the public void onActivate()
{}method.
In my subpage I also have implemented the public void onActivate() {}.
The code in onActivate() of my subpage is executed twice.
BASEPAGE:
public void onActivate() {
String pageName = resources.getPageName();
breadCrumbHolder.checkBreadCrumbForRemove(pageName);
}
SUBCLASS:
public void onActivate() {
logger.debug("OnActivate ");
products = productDAO.findAllByCategory(ProductCategory.Books);
if (logger.isDebugEnabled()) {
logger.debug("Nr of products: " + products.size());
}
}
This is the logging when I acces the page:
[DEBUG] Products OnActivate
[DEBUG] Products Nr of products:: 43
[DEBUG] Products OnActivate
[DEBUG] Products Nr of products:: 43

What version of Tapestry? This was addressed in 5.0.14, I believe, to
ensure that when overriding a base class event handler method, the
method is not invoked twice.

you have to be more specific,
same OnActivate method will not be called more than once in normal
circumastances,
but overriding onActivate from a base class I belive can cause this ...
some code would be useful.
