Getting error as invalid identifier on accessing new columns which added in view on queryentity

Getting error on accessing new columns which added in view recently  on using  queryentity

But this is happening when I use the columns with alias name like below

18-02-20 11:24:39,366 [ajp-/0.0.0.0:8009-4] ERROR org.hibernate.util.JDBCExceptionReporter - ORA-00904: "THIS_"."eorDecision": invalid identifier

ted.createdate thermalDecisionDate,

    eed.decision eorDecision,

     eed.createuser eorName,

When I changed the view columns as below , it started working . Not sure what might be an issue

ted.createdate ,

    eed.decision ,

     eed.createuser ,

Please can someone help me in understanding this.

I am in 16.3 appian version
