Unable to deserialize object when starting a new case of a process
Hi everybody.
I made this step:
1) I defined a BDM com.xyz.Class with only one attribute (a String, mandatory)
2) I defined a process variable "var" of type com.xyz.Class (the class defined in BDM)
3) I made a (VERY) simple process with one simple task which should show the process variable instantiated when starting a new case.
I realized a simple webapp which exposes a REST service for starting a new case, using Bonita engine API. For the code, I look at these examples https://documentation.bonitasoft.com/bonita/7.8/manage-a-process and in particular at the paragraph "Set variables of any type and start a process instance"
Whenever I try to start a new case, always I get this error:
message=Unable to deserialize object
<object-stream>
<object-array>
<long>6223957638235021791</long>
<map>
<entry>
<string>var</string>
<com.xyz.Class>
<id>1</id>
</com.xyz.Class>
</entry>
</map>
</object-array>
</object-stream>
with root cause
com.thoughtworks.xstream.mapper.CannotResolveClassException: com.xyz.Class
Am I wrong? What's the problem? Anyone can help me, providing an example of a process with Object as process variable?
If I replace my com.xyz.Class with a text process variable, the new case starts wthout any problem.
Thank you in advance
Hi,
Business objects are not supported as process variable and must be used as business variables only.
Check the documentation reference for more information.

I tried to sart a new instance using REST API and I got this message
Maybe is it possible create only process variables which are primitive types?
I face the same problem, please help
