Jozef Marko updated DROOLS-3227:
--------------------------------
    Description: 
The decision table output column data type is not stored, if the decision table was generated according to some input data. 

An example of such table is attached  [^auto.dmn] . This table was created in steps below:
- Create new DMN diagram
- Add an Input Data node : *applicant*
- Add a Decision node: *applicant score*
- Connect them
- Define new data type: *tApplicant*.
-- lang:string (Constraints: "c", "java")
-- open source: boolean
- Set *applicant* node data type as *tApplicant*
- Set *applicant score* node data type as *number*
- Open expression editor for *applicant score* node
- Set its top level expression as Decision Table
- Save and download DMN model
- It will be like the attached

{code:xml}
      <dmn:output id="_E6C7E5E6-45C5-4FC2-A37B-69806046893F" name="output-1" typeRef="string">
        <dmn:outputValues id="_B473BAB4-521D-4FD9-88BC-C28CD497F03A">
          <dmn:text></dmn:text>
        </dmn:outputValues>
        <dmn:defaultOutputEntry id="_85BF133E-380C-4F0E-9E2A-0C5C6493F6B4" typeRef="string">
          <dmn:text></dmn:text>
        </dmn:defaultOutputEntry>
      </dmn:output>
{code}

  was:
Issue spotted during DROOLS-3214, however probably not related.

If decision table output data type is changed, the change is not reflected in the xml.

Please follow my steps:
- Create new DMN diagram
- Add a decision node
- Set the decision node top level expression as a decision table
- Double click on Output header cell
- Select boolean lets say
- Save the diagram

Check the source, there will be still stored string output data type, like below:
{code:xml}
<dmn:decisionTable id="_DE6CDA18-99D1-4259-9F6D-825209DF7DE8" typeRef="string" hitPolicy="ANY" preferredOrientation="Rule-as-Row">
      <dmn:input id="_EB7B7C02-4131-468C-B1B1-023C39045B66">
        <dmn:inputExpression id="_C72A9C94-130C-4BA5-A529-49BAE217DDFF" typeRef="string">
          <dmn:text>input-1</dmn:text>
        </dmn:inputExpression>
        <dmn:inputValues id="_1EC58DD6-21EB-4822-A333-581363BC325B">
          <dmn:text></dmn:text>
        </dmn:inputValues>
      </dmn:input>
      <dmn:output id="_81248A6E-0239-404A-B891-C7C0BEE6B501" name="output-1" typeRef="string">
        <dmn:outputValues id="_26301186-9EB2-43E8-B6F8-458361E99B45">
          <dmn:text></dmn:text>
        </dmn:outputValues>
        <dmn:defaultOutputEntry id="_EAC89F66-3B9E-4781-B670-1282975F4F1E" typeRef="string">
          <dmn:text></dmn:text>
        </dmn:defaultOutputEntry>
      </dmn:output>
      <dmn:rule id="_EC0CEE6B-E4D5-4DE2-9EE5-86C955933B4E">
        <dmn:inputEntry id="_91AA6110-0A85-4C95-B0B3-D1B084CB0089">
          <dmn:text>"you are right"</dmn:text>
        </dmn:inputEntry>
        <dmn:outputEntry id="_6FACD1CE-8301-413E-8C77-F04AD71B3C78" typeRef="string">
          <dmn:text>true</dmn:text>
        </dmn:outputEntry>
      </dmn:rule>
    </dmn:decisionTable>
  </dmn:decision>
{code}

But the UI is like:
