Dynamic creation of Layouts

Hi Friends,

I want to create a Matrix Layout like bellow.

var lmain = new sap.ui.commons.layout.MatrixLayout(layoutName, {

  columns : ConfigLine.COL_COUNT,

  width : weit,

  widths : [ '20%' , '80%' ]

  });

var LAYSEARCH = sap.ui.getCore().byId("LAYSEARCH");

var LAYFLUEGE = sap.ui.getCore().byId("LAYFLUEGE");

var ini = [];

ini.push("LAYSEARCH");

ini.push("LAYFLUEGE");

lmain.createRow([ini]);

But it does not work.

Ini shold be all the layouts I created before.

And all of them should be in a row.

Any help would appreciated.
