Question:
Error in subscribeContext

Description:
I'm currently trying to configure the Fiware Iot Broker with the Configuration Manager (NECongMan) and Fiware Orion as the context producer. I'm having a problem with the NGSI10 subscribeContext operation.

This is the request sent to the IoT Broker:

<?xml version="1.0"?>
<subscribeContextRequest>
<entityIdList>
<entityId type="Room" isPattern="false">
<id>Room1</id>
</entityId>
</entityIdList>
<attributeList>
<attribute>temperature</attribute>
</attributeList>
<reference>http://localhost:1028/accumulate&lt;/reference&gt;
<duration>PT1H</duration>
<notifyConditions>
<notifyCondition>
<type>ONCHANGE</type>
<condValueList>
<condValue>pressure</condValue>
</condValueList>
</notifyCondition>
</notifyConditions>
<throttling>PT5S</throttling>
</subscribeContextRequest>

The IoTBroker tries to contact Orion issuing a subscribeContextRequest but the duration string is changed:

<subscribeContextRequest>
<entityIdList>
<entityId
type="Room"
isPattern="false">
<id>
Room1
</id>
</entityId>
</entityIdList>
<attributeList>
<attribute>
temperature
</attribute>
</attributeList>
<reference>
http://192.168.16.178:8080/ngsi10/notify
</reference>
<duration>
P0Y0M0DT0H59M58.157S
</duration>
<notifyConditions>
<notifyCondition>
<type>
ONCHANGE
</type>
<condValueList>
<condValue>
pressure
</condValue>
</condValueList>
</notifyCondition>
</notifyConditions>
<throttling>
PT5S
</throttling>
</subscribeContextRequest>

But Orion gives an error (invalid payload: syntax error in duration string). Do you have any idea how to resolve the issue?
