本文介绍了一种将表格数据绑定到表单的方法，并监听选择模型的'rowselect'事件来实现数据绑定。此外，还讨论了数据绑定及将更新发送到服务器组件的相关工作。

Are there plans to put the binding.js into the 1.0 version? Or am I overlooking a new way of binding the record to a form, and updateing the grid when the form is updated?

Binding grid data to a form:

Listen to the 'rowselect' event of your selection model:
sm.on('rowselect', this.bindData, this, true);

My bindData function looks like so:
bindData : function(sm, rowIdx){
/* retrieve the current row from the data store */
var currRow = ds.getAt(rowIdx);
/* update form elements */
Ext.fly('book-title-form').dom.value = currRow.get('TITLE');
Ext.fly('book-isbn-form').dom.value = currRow.get('ISBN');
Ext.fly('book-keywords-form').dom.value = currRow.get('KEYWORDS');
Ext.fly('book-description-form').dom.value = currRow.get('DESCRIPTION');
}

As far as the data marshalling is concerned and sending updates to a server-side component this is something that Jack is currently working on and something that I know I am looking forward to a lot.
