Re: [Wicket-user] Wicket exceptions?
This is not a Wicket exception: you have made a programming error. Look at com.enterra.vrm.qst.ui.page.reports.validatexl.AppletBasePanel$6.populateItem(AppletBasePanel.java:603) i.e. line 603 in your AppletBasePanel.java file. There is the NPE.

Re: [Wicket-user] Wicket Exceptions
do you have a quickstart?
can you see what version do you use? (390 is not a code line in the code i
am now looking at)
But looking at the code around that line:
try
{
this.xmlReader = new XmlReader(
new BufferedInputStream(resource.getInputStream(),
4000), encoding);
this.input = new FullyBufferedReader(this.xmlReader);
}
finally
{
resource.close();
this.xmlReader.close(); this is 390 i guess
}
then this seems a bit wrong yes..
If there is a problem constructing the XmlReader then that exception is
swallowed and a null pointer is generated
will fix this.

Re: [Wicket-user] Wicket Exceptions
because xmlReader == null
and then a null pointer is thrown. instead of the original exception that
was created somewhere
in the construction of xmlReader.. (thats why it is still null)

Re: [Wicket-user] Wicket Exceptions
also, even though the project is being tested on the internet, I am still in
development mode (which i suppose is default, if not set at all) . it runs
fine on localhost but the behaviour seems to appear once we try accessing
the application from the internet. works without errors for a session but
seems to throw this errors when other session users try to access it

Re: [Wicket-user] Wicket Exceptions
sounds like the reached limit of open-file issue. Should be solved
in the latest versions 1.2 and 2.x versions as far as I know.

sounds like the reached limit of open-file issue. Should be solved
in the latest versions 1.2 and 2.x versions as far as I know.

also, even though the project is being tested on the internet, I am
still in
development mode (which i suppose is default, if not set at all) . it
runs
fine on localhost but the behaviour seems to appear once we try
accessing
the application from the internet. works without errors for a session
but
seems to throw this errors when other session users try to access it

because xmlReader == null
and then a null pointer is thrown. instead of the original exception
that was created somewhere
in the construction of xmlReader.. (thats why it is still null)

Why is the exception swallowed? Finally doesnt swallow it.

do you have a quickstart?
can you see what version do you use? (390 is not a code line in
the
code i
am now looking at)
But looking at the code around that line:
try
{
this.xmlReader = new XmlReader(
new
BufferedInputStream(resource.getInputStream(),
4000), encoding);
this.input = new FullyBufferedReader(this.xmlReader
);
}
finally
{
resource.close();
this.xmlReader.close(); this is 390 i guess
}
then this seems a bit wrong yes..
If there is a problem constructing the XmlReader then that
exception
is
swallowed and a null pointer is generated
will fix this.
