Hi,

I am using two apex pie chart and I am rerendering the output panel using action polar. After a single refresh, the pie chart automatically vanish away.
I am getting this error in console - SfdcCore.js:386 Visualforce Chart: Error loading configuration for chart 'xjid0jid23': TypeError: Cannot read property 'dom' of null.

<apex:outputPanel id = "main">
