How to refresh selectItems during a command action

Question

I am trying to figure out how to modify the selectItems during the processing of a command action. The command action modifies the database and the selectItems needs to be refreshed by this command. However, the selectItems is getting populated before the action method is called. Is there any way to explicitly set the selectItems during the command action?
Here are the pertinant tags on my jsp page:
<h:selectOneListbox value="#{generateDailyFile.selectedFilename}"
binding="#{generateDailyFile.fileListSelect}">
<f:selectItems value="#{generateDailyFile.items}"
binding="#{generateDailyFile.filesSelectItems}"/>
</h:selectOneListbox>
<h:commandButton value="Generate"
action="#{generateDailyFile.doAction}" />
When the page first opens it loads the selectItems from the generateDailyFile.getItems() method. However, when the commandButton's action calls generateDailyFile.doAction() I need to refresh the selectItems.

Answer 1

your selectitems are from the data base i think they have to be latest from the DB......Since they are not working as desired...
----what is the scope of the object you are building the selectitems.If it is session previous instant pravails so the items are the same as before.
OR
--- in the OnPageLoad() make a call to build the select items that gets you a recent copy.
