How to set parameter at page scope

[satyakatti]

Hi All,

I iterate thru a List and build my ExtendedDataTable. On double click of the row, I would like to display additional details pertaining to the selected row.

This by all means I can do by setting property in my backing bean to the selected object and then build additional table/panel based on the object.

But I would like to do this at page scope i.e when user selects a row, I dont want to set property in bean but would like to get the selected object at pagescope and build the table/panel.

Can this be done?

Regards,

Satya

You can pass a parameter within your request by using a4j:actionparam and you don't need to assign it to any variable in a bean because you can simply read any of request parameters from FacesContext. But in this case you will need to handle selection by your self.

Hi,

Handling the selection means I cant use SimpleSelection for the table?

In such case should I have to manually handle the row clicked events by some scripts?

It would be helpful if you can provide some examples.

You should add somthing like this to your dataTable

<rich:dataTable>

                                    <a4j:support action="#{bean.select}" event="onRowClick">

<a4j:actionparam name="itemId" value="#{currentItem.id}"/>

</a4j:support>

       </rich:dataTable>

and then process parameter itemId from request in your bean.select method.
