Did you try stepping through with a debugger to see what was going on? David

Hi,
I'm having some trouble getting my custom appender which extends RollingFileAppender working. I've got my logback config being read and can extend FileAppender w/o issues but when I switch over to RollingFileAppender, I get the following: java.lang.NullPointerException: null at ch.qos.logback.core.rolling.RollingFileAppender.getFile(RollingFileAppender.java:122) ~[org.apache.sling.commons.log:4.0.0]
Here is my config: <appender name="CUSTOM" class="com.mypackage.logging.CustomLogAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>log.%d{yyyy-MM-dd}.log</fileNamePattern> </rollingPolicy> <prudent>true</prudent> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger{36} - %msg%n</pattern> </encoder> </appender>
The only method that I override is writeout() as I needed to handle some particular events. Did I missing something obvious in terms of configuration? Any help is appreciated.
Thanks!
