Collapsed cell disappears

Hi everyone.

I’m trying to use the collapsing functionalities on layout object without success.
In a tabbar cell is attached a “2E” layout. When I click on the “b” cell to collapse it, it simply disappears, without giving me the possibility of expanding it again.
Here is my code :

var tmpLayout = this.tabbar.cells("intervention_ulterieure").attachLayout("2E"); tmpLayout.items[0].hideHeader(); tmpLayout.items[1].setText("Second cell"); tmpLayout.setCollapsedText("b","Second cell");

Here is the result :

I’m using dhtmlx 2.5, the problem occurs on both Firefox 24.0 and Chrome 28.0.1500.95 m

Any idea ?

Hi,

Could you attach the sample that demonstrates the problem ?

Actually I can’t.
Without changing a single line of code nor changing the content, the problem disappeared.
