我对 Apache ISIS 很陌生，我正在尝试通过扩展来添加自定义检票口组件ScalarPanelAbstract。
我有一个接受pageable参数的方法。这pageable是一个由Page number和Page size组成的界面。
//region > findAllWithPage (action)
@Action(semantics = SemanticsOf.SAFE)
public PagedList<Employee> findAllWithPage(
@Parameter(optionality = Optionality.OPTIONAL)
final Pageable pageable) {
return employeeRepository.findByOwner(userTenancyService.owner(), pageable);
}
//endregion
这是使用 action 时的样子findAllWithPage。它只有一个参数，即可分页。
现在，我想做的是让它接受两个参数，Page number并且Page size.
我的问题是，我无法获得两个文本字段的值。这是我得到的错误。

}关于我可以操纵哪些方法来获取两个文本字段的值的任何想法？谢谢。
