ParameterSelector
hi,
i get some strange behaviour when using the parameterselector.
when the corresponding action that sets the desired parameter
to the selector tries to log something i get a NPE from the logger.
Map act (...) {
...
try {
...
}
catch (Exception x) {
getLogger().error(...);
>>>>>>>>>>NPE
...
when i use the same action and the selector without logging anything
then everything is fine.
any ideas

RE: ParameterSelector
Posted by Carsten Ziegeler <cz...@s-und-n.de>.
Hi Michael,
the stacktrace shows that the NPE is thrown in the LogKit - from
the source of the LogKit code, it seems to be that your LogKit
configuration is wrong - perhaps you use a category to log
in your action which has no target?

RE: ParameterSelector
Posted by Carsten Ziegeler <cz...@s-und-n.de>.
Hi,
so this error is not related to the parameterselector but to your
(custom) action, right?
Without the complete code for your action, I can only guess.
If you get a NPE in the line you show below, either getLogger()
returns null or something in your expression passed into the
error() method is null.
But this should have nothing to do with the selector.
