-------------------------------

             Summary: Fix the error "Cannot read property 'index' of null" in visualization page
                 Key: KYLIN-4252
                 URL: https://issues.apache.org/jira/browse/KYLIN-4252
             Project: Kylin
          Issue Type: Bug
          Components: Web
    Affects Versions: v3.0.0
            Reporter: wu.kehua
            Assignee: wu.kehua


If we choose the "-- choose metrics --" firstly, then we can't choose any other metric options.

I analyse this operation will cause the errorĀ "Cannot read property 'index' of null" in visualization page, as follows:
{code:java}
message: "Cannot read property 'index' of null"
stack: "TypeError: Cannot read property 'index' of null?    at http://kylin_server:7070/kylin/js/scripts.min.20191108164741.js:55197:69?    at Object.forEach
{code}
