I'm getting the following error when trying to use the the callbacks
feature of the display tag library to show totals:
java.lang.ClassCastException: [Ljava.util.SortedMap;
at
org.displaytag.decorator.TotalTableDecorator.finishRow(TotalTableDecorator.java:168)
Here's a snippit of the code from the JSP page:
<sql:query var="result" scope="session">
SELECT * FROM PROJECTS
</sql:query>
<display:table name="sessionScope.result.rows"
class="displaytag" export="true" sort="list" pagesize="35"
decorator="org.displaytag.decorator.TotalTableDecorator">
<display:column property="COUNTRY" title="Country" group="1"
sortable="true" headerClass="sortable"/>
<display:column property="STATE" title="State" group="2"
sortable="true" headerClass="sortable"/>
<display:column property="CITY" title="City" group="3"
sortable="true" headerClass="sortable"/>
<display:column property="PROJECT_ID" title="Project ID"
sortable="true" headerClass="sortable"/>
<display:column property="PROJECT_NAME" title="Project Name"
sortable="true" headerClass="sortable"/>
<display:column property="ESTIMATED_COST" title="Estimated"
sortable="true" headerClass="sortable"
decorator="com.foo.project.view.decorator.CurrencyDecorator" total="true"/>
<display:column property="ACTUAL_COST" title="Actual"
sortable="true" headerClass="sortable"
decorator="com.foo.project.view.decorator.CurrencyDecorator" total="true"/>
</display:table>
Here's line 168 of the TotalTableDecorator class that's causing the
class cast exception:
if (getViewIndex() == ((List) getDecoratedObject()).size() - 1)
Any help on a workaround would be much appreciated. Thanks!
