Description of problem:
In From File tab of create page, upload a resource file with json format (but metadata.name is not given), then Create, it pops up a small window wrongly saying:
pod '' already exists
Do you want to replace with the new content?

Version-Release number of selected component (if applicable):
fork_ami_openshift3_userinterface_public_546_222

How reproducible:
Always

Steps to Reproduce:
1. oc login and create project
2. Prepare resource file with json format in local PC
$ wget https://raw.githubusercontent.com/openshift/origin/master/examples/hello-openshift/hello-pod.json

Then remove the "name" line under metadata from the file.

3. Login to Openshift web console, click Add to project --> From File --> Browse, select the json file and Create
4. oc create -f hello-pod.json


Actual results:
3. It pops up small window saying:
pod '' already exists
Do you want to replace with the new content?
                        Replace     Cancel

4. It prompts (it is expected):
The Pod "" is invalid.
metadata.name: Required value: name or generateName is required

Expected results:
3. Should prompt the resource is invalid, as same as CLI in step 4

Additional info:
The result should be same as missing other required field:
E.g. remove only spec.containers[0].name, then repeat above steps, both CLI and web console can show correct message:
Pod "hello-openshift" is invalid: spec.containers[0].name: Required value
