Does it actually store it as a java serialized string? If so, maybe the default variable types are not in the right order. Try debugging the code and putting a breakpoint in DefaultVariableTypes.findVariableType(Object)

Thanks for response.

Yes, it stored as java serialized string. Is this the correct behavior of Activiti engine?

No it is not and it definitely does not behave that way for me.

Saving a String shouldn't create a byte-array… This is only done for non-primitive (and wrappers) and non-String serializables + byteArrays. Are you sure you just used a String as variable value?

Debugging error

Hi, I am getting following error while debugging with h2 database 1.3.175 when I attach the h2-1.3.175.jar file :

Class File Editor
The source attachment does not contain the source for the file Server.class

Also I am not able to see any database entry for ACT_RE_PROCDEF table.

Thanks in advance,

Can you add a bit of background about your issue? What are you trying to do?

Kanchan,

I had this problem some time ago and i figured out that in Groovy's case the usual string is treated as GString and is stored as an object.

you can try this and see if it works
new String("TEST".toString());
