How to use 'HistoricTaskInstance.getTaskLocalVariables'

tamutamu — Tue, 22 Oct 2013 02:23:40 GMT

Hi,In Activiti v5.13, I can't task local values using "HistoricTaskInstance.getTaskLocalVariables()". HistoricTaskInstance histTask = historyService.createHistoricTaskInstanceQuery().taskId(taskId).singleResult(); Map<String, Object> locValues = histTask.getTaskLocalVariables(); // locValue

Hi tamutamu,

It depends on whether the variables are saved with <code>task.setVariable()</code> or <code>task.setVariableLocal()</code>
Maybe this post can help you. It's about the scope of variables:

Thanks aitor!

I read that post.
But, I have not obtain the expected results.

Does'nt <code>Task</code> interface have <code>setVariable()</code> and <code>setVariableLocal()</code>?
<code>TaskService</code> interface has <code>setVariable()</code> and <code>setVariableLocal()</code>.

Since <code>HistoryService</code> also does'nt have <code>setVariable()</code> and <code>setVariableLocal()</code>, I tried to use <code>TaksService.setVariableLocal()</code>.
Below Code,
<java>
　Map<String, Object> inVarMap = new HashMap<String, Object>();
　inVarMap.put("VAL", "val");
　taskService.setVariablesLocal(taskId, inVarMap);

　Map<String, Object> outVarMap =
taskService.createTaskQuery().taskId(taskId).singleResult().getTaskLocalVariables(); // But outVarMap is Empty!!
</java>

However it does not work.
Is This Code wrong?

After ｒun the above code, <code>VAL</code> value is stored in Table <code>ACT_RU_VARIABLE</code>, and the value of <code>Task_ID_</code> field is exist.

Thank you for your advice.

Hi tamutamu.

I don't want to ask you silly questions. The can be many reasons (is History turned on, did you use historyService.createHistoricTaskInstanceQuery().includeTaskLocalVariables() …..?) The best way could be to create jUnit test.

Thanks martin.grofcik!
Explanation is insufficient, and I'm sorry.

I found the cause.
I didn't use <code>includeTaskLocalVariables</code>.

<code>HistoricTaskInstance.getTaskLocalVariables</code> javadoc「if requested 」, it is to call includeTaskLocalVariables in task query, isn't it. I wasn't able to notice that.

Thanks and best regards.
