我对Apache ISIS很陌生，我试图通过扩展ScalarPanelAbstract来添加自定义wicket组件。
我有一个接受pageable参数的方法。 pageable是一个包含页码和页面大小的界面。
//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
这是您使用操作findAllWithPage时的样子。它只有一个可分页的参数。
现在，我要做的是让它接受两个参数Page number and 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。

在扩展PageablePanelAbstract.java的{{1}}上，有三种方法被覆盖：
ScalarPanelAbstract addComponentForRegular(); addComponentForCompact(); PageablePanelAbstract.java
addFormComponentBehavior();
我可以操纵哪些方法来获取两个文本字段的值？感谢。
