Hi All,

We are trying to use TOSCA + UUI + VFC flow for service design and 
instantiation . We are using Casablanca latest release (used the code which was 
updated with branch casablanca recently) . We are referring following 
documentations :
https://docs.onap.org/en/latest/submodules/integration.git/docs/docs_vCPE%20with%20Tosca%20VNF.html?highlight=vCPE
 
https://wiki.onap.org/display/DW/VF-C+R3+operation+guide 
https://wiki.onap.org/display/DW/VF-C+User+Guide

Now problem is when we are trying we are encountering many issues and some are 
very basic issues, when we see the code there is no way it will work as it is. 
Few examples : 

* UUI has some issues. It doesn't show already created instances when we close 
and open. 
* Sync SDC model with VFC is not working (Package on board failure!!) . however 
directly uploading vnf and ns packages working. 
* There are other issues like delete is not working. 
* Multivim is not registering following endpoint in MSB. I manually registered. 
(/api/multicloud/v0) 
* In multivim proxy there was code issue in casablanca which I see is fixed in 
master - Issue-ID: VFC-1366. onap/vfc/multivimproxy:1.2.1 image has the issue 
which can never work. 
* Even after fixing the issue there is another issue - call to API never works 
and call enters into recursive call and never returns. - 
ProxyRoa.java->proxyPost is the method called. 
Also following from design point of view want to know any plan is there to 
enhance VFC which I couldn't see in casablanca release:
* Preload functionality similar to SDNC preload. 
* Integration of policy in the run time (similar to naming policy) 
* Not sure whether VFC will support variety of use cases which SDNC and APPC 
currently supporting like software upgrade , config modify etc. 
* I see there is some poc for PNF , hence was curious any plans to bring 5G PNF 
usecases in VF-C. 
* Is there any plan to use more SO bpmn flows to drive the flow since having 
the flow in the python code difficult to monitor and debug. 

Above questions are for us to understand whether we can use VF-C for service 
instantiation if not now but in the future (dublin or later) . Any help is 
appreciated .
