Well actually I haven't :-) My localizer gets quite large, but it hasnt made
any problems, yet .
You see when the localizer wants to find the resource value for a specific
key, it caches the result into the localizer. Now if your component has a
deep hierarchy, the generated key will be quite large
maybe localizer should limit its size or use a soft reference cache?

Thanks for your all replys.
I review the dump file with both SAP MemoryAnalyzer and YourKit
They all show the same hierachy as follows:
-org.apache.wicket.settings.Settings
- org.apache.wicket.Localizer
- org.apache.wicket.util.concurrent.ConcurrentHashMap
- org.apache.wicket.util.concurren
usually there is a wicket-spring release for every wicket release, can

You should use a Fragment instead of a Panel in that case.

You have got a valid point, but its just tha

okay, so i think the answer to your question is no, you can't optimize that.
you should be using detachable models and an OTS db cache.

if you assigned to that null field (clearly not with the code below) and you
are still getting an NPE, it could not be the /same/ error by definition. i
suggest you slow down, get out a debugger and think this through.

i assigned new Model() to the field.
String sym = (String) new Model().getObject();
int stockValue = sym.hashCode() % 100;
QuoteResult quoteResult = new QuoteResult(stockValue);

and it still threw the same error.

okay, suit yourself, but this is the normal/expected use case for wicket
detachable models, which are the preferred route to go. i think you will
find other options less workable.

Well actually before posting this up, i did try this i.e. mounted the page

against the id) but at that time i had the page as bookmarkable (i.e. had

You do this

this is one good reason, btw, to make your fields final when possible. the
compiler would have warned you.

You should use a writable model like PropertyModel. Read the documentation
for more info.
So i rewrite your code like this:
try this
First, Create a Backing Bean which will hold 2 values, the value of the
TICKER SYMBOL and the value of the Stock Answer
class StockBean implements Serializable {

If it is a statelessform and the page must first be created yes the page

And yes that is ofcourse then all the fields of the form..
And at that point it is a normal bookmarkable request.. after the page is

O
so you compile against 1.4?
then you run against 1.3 because i see that it wants to have the array type
and that is an 1.4 method (varargs)
