Multifield richtext editor
I want to create a multifield richtext editor. I find a article about it (http://blogs.adobe.com/contentmanagement/2013/08/22/customized-multifield-richtext-editor/).
I follow step 1 Creating a multi richText field and get my component. The component works fine for the first time edit. But if you modify the text value (i mean for the second time edit), a js error occurs: Uncaught TypeError: Cannot set property 'value' of undefined
I'm sure I follow the instruction exactly cause it's quite simple (using xtype multifield, add fieldConfig and add xtype richtext). Can anyone try out the instruction and help? Is it an extjs bug? Other workaround suggestion is also welcomed.
Thanks in advance.
