ClassNotFound exception upon domain object deserialization from the context variable #16

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Start new process instance and pass domain object instance as a process 
variable. (ProcessInstance RuntimeService.startProcessInstanceByKey(String 
processDefinitionKey, String businessKey, Map<String, Object> variables);)

2. Stop process execution at user task
3. Try to read process variable (Map<String, Object> 
RuntimeService.getVariables(String executionId, Collection<String> 
variableNames);)
4. See exception:
org.activiti.engine.ActivitiException: coudn't deserialize object in variable

Expected output - map with domain object inside

Hi there,

Thanks for report this issue. Do you want to store GORM entity in process 
variables?

I believe this issue related to discussion topic posted by Ned at 
http://groups.google.com/group/grails-activiti-plugin/browse_thread/thread/b2edd
15bc137c127, yes/no?

Yes, this issue is related to the discussion topic - I want to store GORM 
entity in process variable. Currently this doesn't work due to deserialization 
bug.

Please post your message there, Ned may have solution on it.

Hi there,
I fix this issue for my project. I create class GroovyObjectInputStream that 
extends ObjectInputStream and has not issues with deserialization. And then 
create custom SerializationVariableType and configure it in 
ActivitiGrailsPlugin:

processEngineConfiguration(org.activiti.spring.SpringProcessEngineConfiguration)
 {
   ...
   customPreVariableTypes = [new SerializableActivitiType()]
   customPostVariableTypes = [new SerializableActivitiType()]
}

Lim Chee Kin, please answer - how do we may to contribute this fix?

Best regards, Ilya

Great! Please fork the plugin's source at 
https://github.com/limcheekin/activiti and create a "pull request" when you are 
done.

FYI, I will be off for holiday on next week, so my response will be slower.

Best regards,
Chee Kin

I believe this code change is unncessary, should have implemented 
java.io.Serializable. I included Serializble interface on my 
grails-domain-classes and the issue was resolved.
