ADF tree with command link

Question

Hello,
I have a menu build with a tree and a region. When I click a link from the tree the region populate a page with another dinamic tree based on a session variable that refresh each time that i click a link from the first tree. After click the link I have a flow that has an executewithparams method and the page that will show the second tree.
My problem is that the second tree doesn't refresh its branches at my first click on the link but on the second yes and I receive :
<NavigationPaneRenderer><_renderContent> Warning: There are no items to render for this level
<FormRenderer><setupEncodingContext> Multiple forms detected on viewId: /pages/index.jspx. Rich client currently has some limitations in dealing with multiple forms.
I have set the autorefresh for the iterator but I haven't success.
Can anyone help me?
Thank you.
