How to solve invient chart loading issue

this is my problem. i used invient chart to draw chart in my vaadin application

  1. i used CombinationMultiple chart and i obtained the result. but the main problem i got is that while first time i load the application the chart is displayed and i logout the app and opened again but i does not show the chart.
  2. Also i opened my application in two or three tab and in another browser . the chart not at all show.
    i found a bug through firefox bug report that the problem is with the query i imported like jquery 1.4.js , highchart.js, and in exporting.js file.
