quesion description details :
i complete my assignee-userTask with method formService.submitTaskFormData(String taskId, Map<String, String> properties);
all the values in the properties are actually type of String,this is also restricted by api.
in my process the next node come after userTask node which create assignee-userTask i have handled just now is exclusiveGateway
two sequenceFlow with come from it,the conditionExpressions on the the two sequenceFlow are each as ${vacationApproved} and ${!vacationApproved}
the relevant flow section is like this :
<exclusiveGateway id="requestApprovedDecision" name="Request approved?" />
<sequenceFlow id="flow3" sourceRef="requestApprovedDecision" targetRef="sendApprovalMail">
<conditionExpression xsi:type="tFormalExpression">${vacationApproved}</conditionExpression>
</sequenceFlow>
<task id="sendApprovalMail" name="Send confirmation e-mail" />
<sequenceFlow id="flow4" sourceRef="sendApprovalMail" targetRef="theEnd1" />
<endEvent id="theEnd1" />
<sequenceFlow id="flow5" sourceRef="requestApprovedDecision" targetRef="adjustVacationRequestTask">
<conditionExpression xsi:type="tFormalExpression">${!vacationApproved}</conditionExpression>
</sequenceFlow>
the flow variable ${vacationApproved} is one value of formProperties(Map) which i have submitted to the corresponding userTask ,its type i passed is actually
String,but in the activiti engine its type is required Boolean, the activiti engine cannot transform variable vacationApproved from String
to Boolean automaticly,so the error appeared .
who can help me?
