dhtmlxlayout in Tabbar

I have a tabbar with three tabs. I want to place a dhtmlx Layout in one of them and it does not work

My javascript code is this



function createObservationsInterItemTab(interItemTab){



var intraItemObsdiv = createIDNode(“div”,“intraItemObsdiv”);

interItemTab.setContent(“observationsInter_tab”, intraItemObsdiv);



interItemLayout = new dhtmlXLayoutObject(intraItemObsdiv,“4I”,“dhx_blue”);



interItemLayout.setEffect(“highlight”,false);

interItemLayout.setAutoSize(“a;b;c;d”,“a;b;c;d”);



interItemLayout.cells(“a”).setHeight(“20”);

interItemLayout.cells(“a”).setWidth(“750”);

interItemLayout.cells(“b”).setHeight(“210”);

Please, see attached sample with layout inside tabbar. Possibly it will help to resolve the issue.
