odoo.exceptions.ValidationError: 无效视图.......

bug来源：我需要在tree视图中修改某个图片的大小，因此直接在filed中添加了一个style属性：

<field name="design_img_64" string="图片" widget="image" style="max-width: 30px;max-height: 30px;"/>

到这一步直接刷新界面，正常显示且没报错，但当完成其他功能之后，点击升级按钮，报出以下错误：

错误:

错误分析：

odoo.exceptions.ValidationError: 无效视图任务清单 (decelop_proofing.proofing_task_list_tree_view) 定义，在  decelop_proofing/views/proofing_task_list_view.xml中
首先看这条错误信息是指定义的tree视图无效，且并没有给出无效原因；
经过代码排查和版本回退，发现将style删除后错误解决；

 

总结：odoo14不可以直接在tree中通过style属性修改某个字段的样式，可以尝试使用css或者后台修改图片大小。
