Problems using sorting, defaultsort with version of Displaytag in CVS
---------------------------------------------------------------------
Key: DISPL-237
URL: http://jira.codehaus.org/browse/DISPL-237
Project: DisplayTag
Type: Bug
Components: Paging/Sorting
I am having a problem with sorting using the current version of displaytag in
CVS.
Here is my code:
<c:if test="${sessionScope.listaProcesso!=null}">
<display:table name="sessionScope.listaProcesso" pagesize="10"
requestURI="geraPesquisaProcessoGenerica.do?evento=Paginar" class="lista"
sort="page" defaultsort="1">
<display:column titleKey="label.manter.processo.numero.processo"
property="processoFormatado" paramId="idObj" paramProperty="id"
sortable="true"/>
<display:column titleKey="label.manter.processo.data.inicio"
property="dataInicio" paramId="idObj" paramProperty="id"
decorator="com.synos.egov.licitacao.controller.decorator.DataDecorator" />
<display:column titleKey="label.manter.processo.aglutinacao"
property="aglutinacao.aglutinacaoFormatada" paramId="idObj" paramProperty="id"/>
<display:column titleKey="label.manter.processo.forma.contratacao"
property="formaContratacao.descricao" paramId="idObj" paramProperty="id"/>
<display:column titleKey="label.manter.processo.tipo.contratacao"
property="tipoContratacao.descricao" paramId="idObj" paramProperty="id"/>
<display:column titleKey="label.manter.processo.situacao"
property="situacao.descricao" paramId="idObj" paramProperty="id"/>
</display:table>
</c:if>
When i access the page for the first time it runs perfectly. But in the next
times I have the following errors.
java.lang.NullPointerException
