Hello,


I get a consistent exception when attempting to create a table with
some specific number of columns



Error: [Exception... "'Error: Error in
property maximum of class qx.ui.basic.ScrollBar in method setMaximum with
incoming value '966.6666666666667': Is invalid!' when calling method: 
[nsIDOMEventListener::handleEvent]"
 nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)"  location: "<unknown>"
 data: no]



I traced the problem to the function _updateHorScrollBarMaximum()
in the 
qooxdoo-0.7.1-sdk/frontend/framework/source/class/qx/ui/table/pane/Scroller.js

When call this.getTablePaneModel().getTotalWidth() returns integer everything
works just fine, but sometimes the call returns non-integer and I get the
exception. Is it a well known problem ? 



thank you
