ADF: Passing parameters from one page to another using setPropertyListener

Question

Hi,
I'm trying to find a simple way to pass a parameter from one page to another.
On the first page I have a table, the second page is a history page, showing the change history of rows from the table on the first page.
In the table on the first page there's a unique column (an order number), the value of which is never changed for a given row.
What I would like is to be able to pass the order number from the currently selected row of the first page on to the history page, making the history page show only the history for the given order number.
Using the task-flow for the history page, I've defined an input parameter (an order number), defined a criteria and so on. I've tested the functionality of this in the Application Module, and it seems to work.
My problem is passing the order number from the first page to the second.
I've created a Managed Bean, with a variable for the current order number, including accessors. On the table on the first page, I've created a contextMenu, and added an Item called "Show history" with an action that navigated from the first to the second page (a control flow I've defined in adfc-config). I've included a setPropertyListener in the "Show history" item. I've set the "From" property of the setPropertyListener to "#{row.ordernumber.attributeValue}" and the "To" property to point at the order variable in the Managed Bean. Finally, I created a new page for the history, dragged the history task flow onto this page as a region, using the Managed Bean order variable as input parameter.
The result is this: When I bring up the context menu from a row in the table on the first page and select "Show history", I get this error: "The class 'java.lang.String' does not have the property 'attributeValue'."
That's a bit puzzling to me, seeing as I used the Expression Builder to fill out the "From" property. I've tried using "inputValue" instead of "attributeValue", but that simply changes the error message to: "The class 'java.lang.String' does not have the property 'inputValue'."
What am I doing wrong?
Regards,
Andreas

Hi Timo and Puthanampatti,
I actually tried something similar to what you have suggested before starting this thread, but still got an error. What I hadn't spent a lot of time investigating initially was that it gave a DIFFERENT error. But after reading Timo's suggestion, I went back to this other error and found out that it was connected to my Managed Bean. For some reason, I had made the mistake of giving the bean the same name (in adfc-config) as the actual java class. And this leads to a circular reference error (that I would only get to see when I didn't get the java.lang.String error first).
Having fixed this, I can successfully pass my parameter from one page to another (with the "From" property of the setPropertyListener set to "#{row.ordernumber}").
Thanks for your time,
Andreas
