Manuel Stampe commented on AMDATUMNGMNT-5:
------------------------------------------
With a plain vanilla ACE server I also get the problem. At least I assume it is
the same, because I don't see a log file. First I created a feature via the
vaadin interface, I tried to modify with REST calls. Following I post the curl
commands and their responses:
curl -i -X 'POST' http://localhost:8080/client/work/
{noformat}
HTTP/1.1 302 Found
Location: http://localhost:8080/client/work/work/rest-4
Content-Length: 0
Server: Jetty(6.1.x)
{noformat}
curl -i -X 'GET' http://localhost:8080/client/work/rest-4/feature
{noformat}
HTTP/1.1 200 OK
Transfer-Encoding: chunked
Server: Jetty(6.1.x)
["group-name-newFeature"]
{noformat}
curl -i -X 'GET'
http://localhost:8080/client/work/rest-4/feature/group-name-newFeature
{noformat}
HTTP/1.1 200 OK
Transfer-Encoding: chunked
Server: Jetty(6.1.x)
{"attributes":{"description":"desc","name":"newFeature"},"tags":{}}
{noformat}
curl -i -X 'PUT' -d
'{"attributes":{"description":"UPDATED","name":"newFeature"},"tags":{}}'
http://localhost:8080/client/work/rest-4/feature/group-name-newFeature
{noformat}
HTTP/1.1 500 Internal Server Error

> Project: Amdatu Management
> Issue Type: Bug
> Affects Versions: 0.0.1
> Environment: - Amdatu AMS with opensocial
> - REST call from within opensocial gadget
> Reporter: Manuel Stampe
>
> When I want to update an entity, for example a feature via a REST call, I get
> the NullPointerException below:
> Retrieving a single feature works, like:
> GET http://localhost:8080/client/work/rest-30/feature/group-name-newFeature
> But when I update the very same feature via
> PUT http://localhost:8080/client/work/rest-30/feature/group-name-newFeature
> with the according JSON representation of the object, the error appears.
> In the debugger it seems, that also the entityId is set to "feature" instead
> of its actual name.
