My trigger becames [Cannot evaluate function ] status when the value of items contains double quotation(").

I use log monitoring item key(log) and use the following trigger.
–
({Template_JBossLogMonitor:log[/opt/jboss-6.1.0.Final/server/{$JBOSS_SERVICE_NAME}/log/framework.log,@jboss_framework_log_error_message,UTF-8,1].str(",SYSTEM_ERROR,")})#0
–

When the message which contains double quotation is output in the log file , my trigger becomes [Cannot evaluate function ] status.
Following is the message.
