Ext.ns("Ext.grid.plugins");
Ext.grid.plugins.AutoResize = Ext.extend(Ext.util.Observable, {
init : function(grid) {
var id = grid.getId();
grid.applyToMarkup = function(el) {
grid.render(el);
};
// || Ext.get(grid.renderTo || grid.applyTo).id;
var containerId = 'center';
obj = Ext.getCmp(containerId);
PMS.ctrl.autosize = obj;
var width = obj.getWidth();
var height = obj.getHeight();
grid.setWidth(width - 20);
grid.setHeight(height - 90);
obj.on("resize", function(panel, adjWidth, adjHeight, rawWidth,
rawHeight) {
//通过ID获取对象本身，如果是对象传递当对象关闭后就会出现著名的：this.dom is undefined
var grid = Ext.getCmp(id);
grid.setWidth(adjWidth - 20);
grid.setHeight(adjHeight - 90);
});
}
});

再判断下：
if (grid) {
grid.setWidth(adjWidth - 20);
grid.setHeight(adjHeight - 90);
}
