Hi,
as I was saying in the original post, in rare cases the tree degenerates to a
plain
list - i.e a tree with one (hidden) root node and up to 5000 children that are
rendered
at the same time. Please do not ask me, why our customer would want that - it
is how
it is for the time being ;-)

why is your tree rendering all the nodes ahead of time? shouldnt it
render them lazily as they are expanded?

Hi there,
I am currently encountering a problem that I don't know how to attack... We
have
developed an application that uses the Tree-Component to show hierarchical
data
to the user. In some cases, the tree degenerates to a plain list that can be
quite
large. Now, if the list has around 1000 entries, the rendering phase for the
tree
takes approx. 1 second, which seems to be ok. For 2500 entries, the
rendering time
goes up to around 11 seconds and with 5000 entries, we're looking at approx.
30
seconds.
Now, I would like to find out, which part of the component tree causes these
huge
numbers, but I have run out of ideas on how to track down these numbers. The
last
point I was able to measure was between onBeforeRender and onAfterRender of
my
subclassed LabelTree component.
Any suggestions on how to instrument my application without building a
custom wicket
package?
Kind Regards,
J.
