I use tapestry-hibernate in my apps,
in one page:
<t:grid source="pageList" row="page2">
<t:parameter name="pageIdcell">
<t:actionLink id="pageDelete" context="${page2.pageId}">删除</t:actionLink>
<t:pageLink page="sysadm/editpage" context="${page2.pageId}">更新</t:pageLink>
</t:parameter>
</t:grid>
in editpage.java
void onActivate(String id) {
page = (Page) session.createCriteria(Page.class).add(
Restrictions.eq("pageId", id)).uniqueResult();
}
void onSuccess() {
session.saveOrUpdate(page);
}
when i submit the editpage, i got a error:
Illegal attempt to associate a collection with two open sessions
...
anyone helps?
