[Tapestry-developer] Conditional problem

[Programozás]

Hello!   I have a page with a component in it. The page has a persistent property 'openedFolderId' which I would like to use in the component definition. The component has a property named 'folder'. If I write in the component definition:       <component id="ifFolderOpened" type="Conditional">         <binding name="condition" expression="page.openedFolderId == folder.id"/>     </component> then I get an exception:         ognl.NoSuchPropertyException     folder   BUT if I write:       <component id="ifFolderOpened" type="Conditional">         <binding name="condition" expression="page.openedFolderId == page.components.categories.folder.id"/>     </component> where 'categories' is the name of my component in the page definition then it works!   Help me, what am I doing wrong? Thanks, Norbi
