Hi,
I'm learning Seam and I've crashed against the first problem.
I'm uploading files and it works right, however when I show a list of the files that have been uploaded, I also show a Commandbutton to show all data asociated to the file.
This is the view:
...
<rich:panel>
<f:facet name="header">#{messages['documentos.listado.titulo.tabla']}</f:facet>
<h:outputText value="#{messages['documentos.listado.nodocuments']}" rendered="#{listaDocumentos.rowCount==0}"/>
<h:dataTable var="registro" value="#{listaDocumentos}" rendered="#{listaDocumentos.rowCount>0}">
<h:column>
<f:facet name="header">
<h:outputText value="#{messages['documentos.listado.titulo.title']}"/>
</f:facet>
<h:outputText value="#{registro.fileName}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{messages['documentos.listado.titulo.fechaalta']}"/>
</f:facet>
<h:outputText value="#{registro.uploadDate}" >
<s:convertDateTime pattern="dd/MM/yyyy"/>
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{messages['documentos.listado.ver']}"/>
</f:facet>
<h:form>
<a:commandButton id="verDatos" value="Ver" action="#{publicDocumentAction.verDocumento(registro)}" reRender="seleccionDocumento"/>
</h:form>
</h:column>
</h:dataTable>
<a:outputPanel id="seleccionDocumento">
<rich:panel>
<f:facet name="header">Datos del documento</f:facet>
<h:outputText value="No se ha encontrado un documento" rendered="#{ficheroRetornado==null}"/>
<h:dataTable var="fichero" value="#{ficheroRetornado}" rendered="#{ficheroRetornado!=null}">
<h:column>
<f:facet name="header">
<h:outputText value="Nombre fichero"/>
</f:facet>
<h:outputText value="#{fichero.fileName}"/>
</h:column>
</h:dataTable>
</rich:panel>
</a:outputPanel>
</rich:panel>
...
And this is the action:
...
@DataModelSelection
private Fichero ficheroRetornado;
...
@Begin(join = true)
public void verDocumento(Fichero ficheroView) {
log.info("Llamada AJAX");
if (ficheroView != null) {
log.info("Se obtiene el documento a mostrar: " + ficheroView.getFileName());
this.ficheroRetornado = ficheroView;
} else {
log.error("No se ha indicado un documento a ver correctamente. Los parametros han llegado nulos");
}
}
...
The problem is that when I press the commandbutton, there is no an answer. No mistakes, no incorrect data. Nothing at all.
And when I upload a file I can read the trace "Llamada AJAX"...and I don't know why.
Thank you very much.
