Hi is my first post and im from Brazil,
i have a web system with YUI 2.9.0 and Zend framework, and i have this error

Uncaught TypeError: Cannot call method 'removeChild' of null ....................datatable-min.js:1
h.extend._destroyColumnResizerProxyEl....................................... ................datatable-min.js:15

I'll describe my actions to get this error:
I have YUI grids in the main page and i can reorder columns without this error, but when i open a YUI panel and inside have other's YUI grids and I can also reorder columns, but when i close this panel and try to reorder columns of the YUI grids in the main page i get this error and the grid lock then i don't make nothing on this grid and worse when I try sort rows in the YUI grids on the main page, the sort function is subscribed for me, i get this page: "http://localhost/trafegusweb/main/yui-dt147-href-viag_codigo".

I dont understand what is happening? Any can help me in this problem?

The "viag_codigo" is the column sorted in the grid. The others grid in YUI panels work normally is only grids in the main page where i get this error. The YUI grids in the YUI panels are generated dynamically on the click in menu or buttons. All actions of the grid search directly from the server including paging.

Is my first topic, excuse the errors of english;
