Hi,

I read the table documentation as well as the cross table specific documentation but I can't get it working.

I do have an Xtext Textual language and for a small subset of it I would like to use Cross-Tables

The metamodel is the following
DecisionTableDeclaration
	columnsDeclaration : ColumnDeclaration
	decisions : Decision
ColumnDeclaration
	name : EString
	typeName : EString
Decision
	columnAssignements : ColumnAssignment
ColumnAssignment:
	column : ColumnDeclaration
	val : EString


Here is the model instance
decision table {
		column col1 : string,
		column col2 : string,
		column col3 : string
		
		decision : col1 = "val11", col2 = "val12";
		decision : col1 = "val21", col2 = "val22";
		decision : col1 = "val31", col2 = "val32";
		decision : col1 = "val41", col2 = "val42"	
}


The viewpoint decription currently looks like:
<?xml version="1.0" encoding="UTF-8"?>
<description:Group xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:description="http://www.eclipse.org/sirius/description/1.1.0" xmlns:description_1="http://www.eclipse.org/sirius/table/description/1.1.0" name="blabla" version="11.0.0.201601261200">

      <ownedLineMappings name="Decision" domainClass="Decision" headerLabelExpression="D"/>
      <ownedCreateLine mapping="//@ownedViewpoints[name='BlaBlaInstance']/@ownedRepresentations[name='DecisionTableDeclaration']/@ownedLineMappings[name='Decision']">
        <variables name="root" documentation="The semantic root element of the table."/>
        <variables name="element" documentation="The semantic currently edited element."/>
        <variables name="container" documentation="The semantic element corresponding to the view container."/>
      </ownedCreateLine>
      <ownedColumnMappings name="Column" headerLabelExpression="[name  + ' : ' + typeName/]" domainClass="ColumnDeclaration"/>
      <intersection name="Value" lineMapping="//@ownedViewpoints[name='BlaBlaInstance']/@ownedRepresentations[name='DecisionTableDeclaration']/@ownedLineMappings[name='Decision']" columnMapping="//@ownedViewpoints[name='BlaBlaInstance']/@ownedRepresentations[name='DecisionTableDeclaration']/@ownedColumnMappings.0" labelExpression="[val/]" useDomainClass="true" columnFinderExpression="[column/]" domainClass="ColumnAssignment"/>
    </ownedRepresentations>
  </ownedViewpoints>
</description:Group>


I do get the correct number of lines and the column are labelled as expected but the cells are empty and I did not find how to fill the following properties properly:
- line finder
- column finder
- Label expression.

Does someone have a clue or an example to follow

Thanks for your time
Steve

Hello,

Here is the documentation about Intersection Mappings definition [1].

It seems that the only missing field is the line finder expression. I
guess that in your metamodel, the reference columnAssignements (there is
a typo here) in Decision is a "containment" reference so the line finder
expression should only be "[eContainer()/]".
In "use Domain class" mode, as the cell in your tab represent a semantic
element, you need to set the line finder expression.

Regards,
Steve

Hello and thank you for your help.

Here is a screenshot of the model that might help https://s32.postimg.org/cebfpbgmp/Capture.png

I did add the line finder but now when I validate I get the following errors:
- unrecognized variable val
- unrecognized variable column

So I guess that the column finder and the label are not correct.
To be honest reading the intersection mapping section does not help me much. I am probably missing an important thing.

Thanks in advance for your help
