Hey. Caught this exception. Unknown reason, and it’s too deep in nifty for me to follow it.
What has happened before this, is i’ve changed/started/stopped screens. Initiated by a mouse click. To be more specific, i’ve started a mission in Hostile Sector.

@erlend_sh: It was not looked into this since - for a couple of weeks now - the forum refuses do sent me notifications for some reason. Normen said that this was a known issue that was fixed in the meantime but it doesn’t worked for me yet unfortunately.
@rickard:
It seems like there is some onClick() method somewhere that is not accepting String parameters but some other parameters. It crashes somewhere in this method:
[java] private Object callMethod(final Object targetObject, final Method method, final Object[] invokeParameters) {
try {
log.fine("method: " + method + "on targetObject: " + targetObject + ", parameters: " + invokeParameters);
if (method != null) {
log.fine(method.getName());
}
if (invokeParameters != null) {
for (Object o : invokeParameters) {
log.fine("parameter: " + o);
}
}
return method.invoke(targetObject, invokeParameters); // <— NiftyMethodInvoker.java:145
} catch (RuntimeException e) {
[/java]
I think when you enable logging for the class de.lessvoid.nifty.NiftyMethodInvoker with FINE log level then Nifty should tell you exactly what method it tries to call on which object right before the exception:
[java] log.fine("method: " + method + "on targetObject: " + targetObject + ", parameters: " + invokeParameters);[/java]

Hmm, that's odd. It should definitely be fixed now. Do note, we're using a new e-mail now, noreply at hub.jmonkeyengine.org. I suggest you search for it and make sure the messages aren't ending up in your junkmail folder because of the new e-mail address.
@erlend_sh: no luck with the spam folder 
but I’ll bug you about that somewhere else so that we don’t spam this thread with unrelated issues : )
Hey.
Didn’t see this topic updated until now 
I don’t remember now if i’ve made a work around for it, or if it’s very rare. But i’ll take this info and see if i can repeat it with fine loggin enabled.
