issues about setting multiple variables

changxl — Tue, 02 Aug 2016 14:55:38 GMT

Hi, I am a developer who has used activiti for 3 years.Recently I tried to upgrade my older version(5.13) to 5.21.0 and I had some big problems, all my code are throwing exceptions at runtime! I worked hard to find the reason for 2 days. I 've tried many versions of activitiand studied the source

I also tried the set methods
runtimeService.setVariable(processInstance.getId(), "var1", "value1");
runtimeService.setVariable(processInstance.getId(), "var2", "value2");
or
taskService.setVariables(task.getId(), MultivariableMap)

and met the same problems, Maybe there's another way I haven't find?

Hi,

I have checked org.activiti.engine.test.api.variables.VariablesTest#setUp. The setUp method performs exactly the same scenario as you describe (set variables, start process) and it works fine (on h2 db).

@Joram: Is the build failing on the Oracle DB?

Martin

I just tested in version 5.19.0 .Here is my code.
<java>
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:spring/spring-activiti.xml",
"classpath*:spring/spring-datasource-test.xml", "classpath*:spring/spring-transaction.xml" })
public class VeriablesTest {

@Resource
private RuntimeService runtimeService;

@Test
public void simpleSpringTest() throws Exception {
Map<String, Object> variableMap = new HashMap<String, Object>();
variableMap.put("var1", "var1");
variableMap.put("var2", "var2");
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("CanotSerializable", variableMap);
}
}
</java>

Here is the config:

Hi,

I used upstream/Activiti6. Could you create jUnit test https://forums.activiti.org/content/sticky-how-write-unit-test

Dear Martin
I have followed your instruction and created Junit test and I found everything worked correctly! So I back to my project and inspected my pom.xml file carefully.
finally I found my mybatis-spring dependency's version is 1.1.1,and It's a very old version and maybe has some conflicts with activiti's mybatis dependency.When I changed it to 1.3.0 ,everything worked correctly!（But still I don't know the exact reason）
Thank you for your help!I appreciate it very much
