[SalesForce] immediate=”true” translated into html

Buried in the order of execution for visualforce postback requests section of the docs is this nugget of information:

During a postback request, the view state is decoded and used as the basis for updating the values on the page. Note: A component with the immediate attribute set to true bypasses this phase of the request. In other words, the action executes, but no validation is performed on the inputs and no data changes on the page.

So if you use immediate, it doesn't just skip the validation, it also discards the user input.

I think your problem should be solved by moving the actionFunction inside the actionregion - otherwise it will be posting back the entire form, including any required fields, rather than just your selected components.

Well Pankaj whenever you are setting immediate="true" for a command button the validations along with the setter for the fields doesnt fire and hence data is not posted to server/controller.

You can also try to enclose sections inside <apex:ActionRegion> this will allow you submit the corresponding section to the server.

Something like this probably

<apex:repeat value="{!listVal}" var="record"/>
    <apex:ActionRegion>
      <apex:outputPanel id="panel">
          <apex:repeat value="{!Fields}" var="f">
            <apex:inputField value="{!record[f]}" required="{!OR(f.required,f.dbrequired)}" />
          </apex:repeat>

            <apex:commandbutton value="submit" action="{!save}" rerender="panel" />
     </apex:outputPanel> 
   <apex:ActionRegion>
</apex:repeat>
