In my project, on click of checkbox and add more button, I am trying to add one row and on click of remove button, remove exact row.
Sometimes I get wrong parameter values in controller methods. So the whole component generation logic isn't working properly.
Index.xhtml
<h:form>
<h:panelGroup id="shipmentTermsBox">
<c:forEach items="#{postOffer.shipmentTerms}" var="shipment" varStatus="shipmentCount">
OuterIndex : #{shipmentCount.index}
<h:selectBooleanCheckbox value="#{shipment.status}">
<f:ajax event="change" listener="#{postOffer.addShipmentTermsRow(shipmentCount.index)}" render="shipmentTermsBox" />
</h:selectBooleanCheckbox>
<label for="stayin">#{shipment.name} </label>
<br/>
<table border="1">
<c:forEach items="#{shipment.shipmentRowList}" var="shipmentRow" varStatus="shipmentRowCount">
<tr>
<td>
InnerIndex : #{shipmentRowCount.index}
</td>
<td>
#{shipmentRow.priceChoice}
<h:selectOneMenu value="#{shipmentRow.priceChoice}">
<f:selectItem itemValue="Above Price" itemLabel="Above Price"/>
<f:selectItem itemValue="+ (more)" itemLabel="+ (more)"/>
<f:selectItem itemValue="- (more)" itemLabel="- (more)"/>
<f:ajax event="change" listener="#{postOffer.processPriceDiffChoice(shipmentCount.index,shipmentRowCount.index)}" render="shipmentTermsBox"/>

<h:commandButton value="Remove">
<f:ajax event="action" listener="#{postOffer.removeShipmentTermsRow(shipmentCount.index,shipmentRowCount.index)}" render="shipmentTermsBox"/>

What I am doing wrong? Is there any logical bug in my code?
