I would like to know how to set up or customize

gmf.compartment.layout = “rowlist”

“free”

“list” nodes in vertical order V
(1)
(2)
(3)

1.- Request
“rowlist” nodes in horizontal order ESSENTIAL!!! order >
(1)(2)(3)

2.- Filling first columns (proposal)
2.a.- “column.down-row.right” order v >
(1)(4)(7)
(2)(5)(-)
(3)(6)(-)
2.b.- “column.up-row.right” order ^ >
2.c.- “column.down-row.left” order V <
2.d.- "column.up-row.left" order ^ v
(1)(2)(3)
(4)(5)(6)
(7)(-)(-)
3.b.- “row.left-column.down” order ^
3.d.- “row.left-column.up” order < ^
(-)(-)(7)
(6)(5)(4)
(3)(2)(1)

4.- Random access (proposal)
matrix
(5)(2)(7)
(4)(-)(6)
(-)(1)(3)

I would need implement an ordered list of rows of ordered nodes.
How could I do? If someone could help me, I would thank it.

Thanks a lot.

Reproducible: Always

Steps to Reproduce:
I was thinking in this metamodel ... 
pay attention to @gmf.compartment(... layout="rowlist") in "LineElement[*] elements;"

@namespace(uri="matrix", prefix="matrix")
@gmf(foo="bar")
package org.mddlab.ox.view;

@gmf.diagram(foo="bar")
class View {
	@gmf.compartment(foo="bar", layout="list")
	val  Line[*] lines;
}

@gmf.node(label="yOrder,titleLine", label.pattern="line({0}) {1}")
class Line {
        attr Integer        yOrder;
        attr String         titleLine; 

        @gmf.compartment(foo="bar", layout="rowlist")
	val  LineElement[*] elements;
}

@gmf.node(label="xOrder,nameReference", label.pattern="order({0}) {1}")
class LineElement {
        attr Integer   xOrder;
	attr String    nameReference;
}


But in order to solve a general problem, we can need also:
@gmf.compartment(layout=...)

Implemented
“free”
“list”    (== column.down)

Request (essential)
“rowlist” nodes in horizontal order ESSENTIAL!!! order >
          (== row.right)

Proposal (behauvior similar to a <table><tr><td>)

“column.down”  order v  (== "list")
“column.up”    order ^

“row.right”    order >  (== "rowlist")
“row.left”     order <

“column.down-row.right”  order v >
“column.up-row.right”    order ^ >
“column.down-row.left”   order v <
"column.up-row.left"     order ^ <

“row.right-column.down”  order > v
“row.right-column.up”    order > ^
“row.left-column.down”   order < v
“row.left-column.up”     order < ^

"matrix"                 random access (as default value “row.right-column.down” )

Thanks
