Error while onWindowResize() event

[kiwon34]

Hi param,

I'm using version 5.0.1 right now.
  I'm facing an error while refreshing after the onWindowResize() event is called.
->'Uncaught TypeError: Cannot read property 'wdCenter' of undefined' error is called.

'this.dims' object cannot be called as below.

pqgrid.dev.js:5913
refreshColumnWidths: function(ui) {
   contWd = this.dims.wdCenter,   -> this.dims is undefined
}

pqgrid.dev.js:5922
Uncaught TypeError: Cannot read property 'wdCenter' of undefined
    at pq.cRenderBody.refreshColumnWidths (pqgrid.dev.js:5922)
    at pq.cRenderBody.init (pqgrid.dev.js:19994)
    at $.paramquery.cRefresh.refresh (pqgrid.dev.js:7426)
    at pqgrid.dev.js:7377

Could you tell me if this is a bug or I'm doing something wrong?

I'm unable to reproduce the error in the demos.

Would you mind sharing the steps or a test case to reproduce this error.
