修改Ext.ux.form.FileUploadField变形问题
在css里加入

/*add*/.x-form-file-wrap-small {    height: 22px ! important;}.x-form-file-wrap-small .x-form-file {    height: 22px ! important;}.x-form-file-wrap-medium {    height: 30px ! important;}.x-form-file-wrap-medium .x-form-file {    height: 30px ! important;}.x-form-file-wrap-large {    height: 38px ! important;}.x-form-file-wrap-large .x-form-file {    height: 38px ! important;}

在Ext.ux.form.FileUploadField的onRender加入

this.wrap.addClass('x-form-file-wrap-'+this.button.scale);
