This is with regard to activiti workflow timer jobs in grails application.

While starting the grails app with expired jobs, exception is thrown for normal grails features such as log and methods of domain classes.

For eg:

Caused by: groovy.lang.MissingPropertyException: No such property: log for class: com.service.common.UtilityService
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:49)
at org.codehaus.groovy.runtime.callsite.PogoMetaClassGetPropertySite.getProperty(PogoMetaClassGetPropertySite.java:50)
at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGroovyObjectGetProperty(AbstractCallSite.java:239)
at com.service.common.UtilityService.insertToQueue(UtilityService.groovy:370)

This happens in dev environment running the app from Spring STS. We are using activiti plugin 5.8.2 for grails (1.3.6)

After the web-app is started up completely, the jobs (schedule to a time after startup) run properly and no missing property exception is thrown.

Even though we can fix the of missing property issue for log by using "private static final log = LogFactory.getLog(this)" instead, then any reference to domain classes throw an error, like using get or find method.

eg:

Caused by: groovy.lang.MissingMethodException: No signature of method: static com.domain.wr.WorkRequest.read() is applicable for argument types: (java.lang.String) values: [44700]
Possible solutions: getId(), getAt(java.lang.String), setId(java.lang.Long), grep(java.lang.Object), each(groovy.lang.Closure), find(groovy.lang.Closure)

Activiti Configuration

Config.groovy

// Added by the Grails Activiti plugin:
activiti {
processEngineName = "activiti-engine-default"
databaseType = "oracle"
deploymentName = appName
history = "audit" // "none", "activity", "audit" or "full"
sessionUsernameKey = "username"
useFormKey = true
deploymentResources = ["classpath:activiti/escalation/WorkRequest.bpmn20.xml"]

}
Config.properties

activiti.processEngineName =activiti-engine-default
activiti.databaseSchemaUpdate =true
activiti.jobExecutorActivate =true
activiti.mailServerHost = "mail1.net"
activiti.mailServerPort = 25
activiti.mailServerUsername = ""
activiti.mailServerPassword = ""
activiti.mailServerDefaultFrom = ""
This is killing my application as a downtime makes the workflow unusable with timer tasks.

Please help.

Thanks Abdul
