Hi Julien,
When the submitted data is processed setSelectedClientTemp will be
called once for each row in the table where the selected value has changed.
In this setter method, you can use the clientsAndQuantities binding to
access the UIData component, and from that can call things like:
* getRowData -- returns the current element from the
listOfMiddleFormHelpers list
* getRowIndex -- returns the current index into the
listOfMiddleFormHelpers list (ie the current table row). You could then
use this as in index into a separate list of selectedClient values.
However a more elegant solution (IMO) would be to write a simple wrapper
class that holds both the selectedClientTemp value and a reference to a
MiddleFormHelper object. The dataTable value can then refer to a list of
these objects rather than a list of MiddleFormHelper objects and all the
components in the columns can then be written using just the "line"
variable and no binding is needed.
Hope this is the info you needed..
Regards,
Simon

Hello all,
I have a dataTable and have developped a method that dynamically adds
rows to the dataTable. Each row is made up of two form controls. The
problem I have now is that I don't know how to retrieve the values from
the mutiple rows. Ideally I would need the values to be stored into a list.
Can anyone help?
Thanks in advance,
Julien.
Here is my code:
[code]
<h:dataTable var="line"
binding="#{TradeClientsAndQuantitiesBean.clientsAndQuantities}"
value="#{ TradeClientsAndQuantitiesBean.listOfMiddleFormHelpers}">
<h:column>
<f:facet name="header">
<h:outputText value="Sélectionnez un client"/>
</f:facet>
<h:selectOneMenu
value="#{TradeClientsAndQuantitiesHelperBean.selectedClientTemp}">
<f:selectItems
value="#{TradeClientsAndQuantitiesHelperBean.concatenatedLabelMap }"/>
</h:selectOneMenu>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Renseignez une quantité"/>
</f:facet>
<h:inputText value=""/>
</h:column>
</h:dataTable>
[/code]
