Hi All,
I've made huge progress on this and I'm so close to a solution it's killing me!
I have a <display:table ..> tag that iterates over a list of beans
(DriverShift) in the usual way. Each of those beans has an attribute that is a
treemap of nested beans (JourneySegment) which are used to build some
additional (dynamic) columns in my table. That much is
working fine.
My final problem is that I want to produce a link in my dynamic column using a
value from the JourneySegment bean. I'm trying to do this
using the paramId and paramName attributes of the <display:column ..> tag.
I've googled and read extensively and spent hours on trial-
and-error, but I am having a problem getting my head around the interplay
between OGNL and EL and I believe that's where my problem
lies.
The following code illustrates where I'm at. To make it a bit easier to
follow, I've pruned out irrelevant "noise". What I'm trying to do is to
get the dynamic <display:column tag to produce a link url containing "?id=xxx"
where the "xxx" value comes from my JourneySegment
bean's deliveryId attribute as the value.
<display:table name="driversShifts" class="table" requestURI=""
id="driversShifts" export="true" pagesize="25">
<..>
<%-- Iterate through the journeySegments if present and display a
Product and ETA column for each --%>
<s:if test="#attr.driversShifts.journeySegments != null &&
#attr.driversShifts.journeySegments.size() > 0">
<s:iterator id="journeySegment"
value="#attr.driversShifts.journeySegments.values()" status="rowStatus">
<%-- expose the current column's deliveryId via a column-specific variable
so <display:column can see it? --%>
<s:set name="deliveryIdParamName"
value="'deliveryId_${driversShifts_rowNum}'"/>
<s:set name="#deliveryIdParamName" value="deliveryId"/>
<s:if test="product != null">
<display:column sortable="false"
titleKey="delivery.product" href="editDelivery.html" paramId="id"
paramName="${deliveryIdParamName}">
<s:property value="product"/><br />
<s:property value="fromLocation"/> to
<s:property value="toLocation"/>
<!-- Delivery ID Param Name :
<s:property value="#deliveryIdParamName"/> -->
<!-- Delivery ID Param Value :
<s:property value="${#deliveryIdParamName}" /> -->
</display:column>
<display:column sortable="false"
titleKey="delivery.arrivalTime">
<fmt:formatDate value="${eta}"
pattern="${timePattern}"/><br />
<s:property value="toLocation"/>
</display:column>
</s:if>
<..>
</s:iterator>
</s:if>
What can I put in the <display:column ..> tag's paramName attribute so it can
see my deliveryId variable's value?
TIA,
