      Description

      Steps to reproduce.

      1. Start ESB with sample 360.
      2. Go to source view and delete the – column="id" – part from the synapse config, in the following fragment
      <statement>
      <sql>call getid;</sql>
      <parameter expression="//m0:getQuote/m0:request/m0:symbol"
      xmlns:m0="http://services.samples" type="VARCHAR"/>
      <result name="company_id" column="id"/>
      </statement>

      3. click Update. It will save WITH OUT WARNINGS.
      4. When the source is updated you will get the error page as shown in the screen shot. After that the source view becomes unusable. Issue exists even though the server is restarted.
