动态 平添 fieldSet

动态 添加 fieldSet
XML/HTML代码

//Create the Form      testForm = new Ext.form.FormPanel({          name: "form1",          frame:true,          width: 350,          items: [{              xtype: "textfield",              name: "nom",              fieldLabel: "nom",              allowBlank: false          }]              });      //Render the form      testForm.render(Ext.get('idForm'));          //Create the fieldset      testFieldSet = new Ext.form.FieldSet({          name: 'testFieldSet',          autoHeight: true,          items: [{                  xtype : "textfield",                  name : "testtextvalid",                  fieldLabel: "testDyn",                  allowBlank: false              }]      });      testForm.add(testFieldSet); //add the fieldset to the formpanel         testForm.doLayout();    ===========this is the workaround============           testFieldSet.form = testForm.getForm();      testForm.initFields.call(testFieldSet);      //delete testForm.form;原来是有这一行的，但加上后连getForm()都不好用了，去掉就没问题了    ===========this is the workaround============   OK，一切恢复正常！

=================================================================================================


workaround部分仅对动态增加FieldSet时有用，而如果被添加的FieldSet可以被删除（remove或者destroy）时，校验仍然会产生错误的，此时必须将FieldSet中的每一个Field在BaseForm中remove掉。
代码如下

var f = fieldset.form || fieldset.ownerCt.getForm();fieldset.items.each(function(item) {    f.remove(item);});fieldset.destroy();
