It seems there is some compatibility issue between WebTab and WebTextEditor issue. A bud report has been sent to our developer. We will will inform you if there is any update on this issue.

is there a work arround?

like preesing html buuton and then design in code or script?

The workaround does work. We could force the WebTextEditor to HTML view and back to design view to display the toolbar. Here is the snippet to change the WebTextEditor view during WebTab after tab changed client side event:

function WebTab1_OnAfterTabChanged(controlId, activeTab, previousTab)
{
	var WebTab1 = ISGetObject(controlId);
	if (activeTab.Name == "TextEditorInlineContent") {
	    var textEditor = ISGetObject("WebTextEditor1");
	    textEditor.SwitchToHtmlView();
	    textEditor.SwitchToDesignView();
	  
	}
	
	return true;
}
