Yang UI Running parametrized request from Histroy tab results in error

Repro steps:
1. Dlux -> Yang UI
2. Expand network-topology rev.2013-10-21 in API tree ->
-> Expand config -> Expand network-topology -> Click topology

3. Click + button to add topology id. Insert "t1" to topology-id input field, execute PUT operation.
4. Go to Parameters tab, add Parameter with name: p1; value: v1.
5. Go to History tab, open Sent data box of the operation of putting t1 topology.
6. Replace "t1" key in yang code with <<p1>> parameter, click Save parametrized data.
7. Click Run this request to run request with parametrized data.
8. Expected result: API is /config/network-topology:network-topology/topology/v1 and Request is sent successfully.
9. Buggy behaviour: API remains /config/network-topology:network-topology/topology/t1, however topology-id in yang is changed to v1.
