How to bind SelectManyChoice to Integer array parameter

Question

Hi.
I am using JDev TP4. I need to populate an integer array with the keys of the items selected in a SelectManyChoice.
I have created a page with a parameter form for the three parameters and a readonly table for the result class from a data control for this method:
public FreeGuaranteeModel[] getFreeGuarantees(Timestamp firstDate, Timestamp lastDate, Integer[] companyIds)
In the parameter form i have created a SelectManyChoice which displays a list
from a viewObject by dragging the companyIds parameter onto the parameter form, creating a SelectSingle component and then converted it to a SelectManyChoice.
The page renders ok, I can select one or more items in the list, but when I press the button to execute the method, the companyIds array is empty.
(The two date parameters are populated).
What am I missing? Is the binding wrong? I am new to JDev so if there is some other way to do this, please let me know.
This is the relevant part of the jspx:
<af:selectManyChoice value="#{bindings.companyIds.inputValue}"
          label="#{bindings.companyIds.label}"
          shortDesc="#{bindings.companyIds.hints.tooltip}"
          binding="#{backing_ViewFinancialResult.selectOneListbox1}"
          id="selectOneListbox1">
<f:selectItems value="#{bindings.companyIds.items}"
     binding="#{backing_ViewFinancialResult.selectItems1}"
     id="selectItems1"/>
</af:selectManyChoice>

Answer 1

Hi,
Thank you for your answer.
Following the example I was able to get the selected entries into an Integer array property with accessors which I created in a managed bean.
But I have not been able to get the values into the companyIds parameter of the method to execute.
Is there a way to bind directly to this parameter, or do I have to collect all parameters through separate properties and then call my method manually when the button is pressed?
