javax.el.PropertyNotFoundException:类'没有可读的属性'preference' [英] javax.el.PropertyNotFoundException: The class ' does not have a readable property 'preference'
问题描述
我已经解决了几乎所有与SO有关的问题，但是找不到答案，因为我没有其他导致错误的原因，而我仍然有相同的错误结果.
I have been through almost all the related questions on SO but couldn't find the answer because I don't have the issues that were the cause of errors for other still I've same error result.
我已经实现了一个primefaces selectBooleanButton 元素，并且仅按此包括了bean代码.该错误意味着系统无法读取ManagedBean的属性，但是我有正确的getter/setter方法，因为它应该用于boolean属性.下面是供参考的代码:
I have implemented a primefaces selectBooleanButton element and included the bean code as per that only. The error means that the system is unable to read the property of the managedBean but I have proper getter/setter methods as it should be for boolean property. Below is the code for reference:

推荐答案
这个问题已经很长时间了，但发布此答案只是为了提及原因并解决问题.
It been a long time for this question but posting this answer just to mention the cause and close the issue.
glassfish没有选择更改并重新启动它可以解决此问题. 因此，如果您确定所做的更改仍然出现错误，我想也可以怀疑服务器了:)
It was glassfish not picking up the changes and restarting it resolved the issue. So, if you are sure about your changes and still getting an error, I guess its ok to doubt the server too :)
