I am facing problem with default values for date fields in generated task forms.
In the start form I specify a date value.
<bpmn:startEvent id="StartEvent_1">
<bpmn:extensionElements>
<camunda:formData>
<camunda:formField id="goal_date" label="Goal Date" type="date" datePattern="yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" />
</camunda:formData>
</bpmn:extensionElements>
</bpmn:startEvent>
It seems to me, that the variable is getting stored correctly as a date value in the database when the process gets instantiated .
select var.name_, var.type_, var.long_
from act_ru_variable var
where name_ = 'goal_date';
| name_ | type_ | long_ |
|---|---|---|
| goal_date | date | 1529445600000 |
A subsequent task form is specified with goal_date as default:
<bpmn:userTask id="approval" name="Approval" camunda:assignee="${requester}">
<bpmn:extensionElements>
<camunda:formData>
<camunda:formField id="new_goal_date" label="New Goal Date" type="date" defaultValue="${goal_date}" datePattern="yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" />
</camunda:formData>
</bpmn:extensionElements>
</bpmn:userTask>
If I try to retrive the form data like so:
this.formService.getTaskFormData(taskId);
I am getting this error:

I don’t know if this is related to the datePattern setting. I was trying to omit the datePattern attribute on the user task but it results the same error.
