Problem With selectOneMenu

[sree lekha]

Hi
I am populating data for my dropdown from database,data gets poplated but am getting a validation error for the selectOneMenu id: value is not a valid option.

<h:selectOneMenu value="#{menuSelection.dailyZReportSummaryBatchId}" id="batchId" converter="javax.faces.Long">
<f:selectItems value="#{menuSelection.batchDetails}" />
</h:selectOneMenu>

I think the problem is that selectItems return a Collection of SelectItem instances, but i have declared selectOneMenu value as Long.

I am not sure that this is causing the error..

how do i solve this...
