seam中复合主键调用问题

seam中复合主键调用问题5

在表form中有三个主键：formid,tabid,operaid
要在页面中可以按照这三个主键中的任意一个查询表中的信息，程序执行后报错：javax.el.PropertyNotFoundException: /FormList.xhtml @23,75 value="#{formList.form.formid}": Property 'formid' not found on type app.ejb.domain.ProjectsManager_SEAM.model.Form

现在有两个实体类，分别是Form.java和Form.java
类定义如下：
