A Seam example with RichFaces?

[manuel.gentile]

Hello,
I think it is useful to have an example of using Seam with richfaces. In particular with drag and drop features.
I have some problem with this and the RichFaces people didn't give me a solution. The richfaces example works... but i use
Seam+Facelet+Richfaces from CVS and I'm not able to use the drag and drop features.....

Thanks

seam-gen will generate a richfaces-enabled app, but it doesn't make use of drag and drop. I don't know which examples will be updated for Richfaces in 1.2.1, but you can expect to see more and more Richfaces in them over time.

I'm using DnD for a "map your columns to our columns" type scenario with the latest Seam + Facelets + Richfaces. Up until yesterday when the Richfaces snapshot seemed to break with JSF 1.2 (http://jboss.com/index.html?module=bb&op=viewtopic&t=104731) it worked extremely well. Here's a summary:

 <rich:dragIndicator id="indicator" />
 <s:link action="#{feedMapping.hideEmptyFeedColumns}" value="Hide Empty Columns" rendered="#{empty feedMapping.hiddenEmptyFeedMappingColumns}"/>
 <s:link action="#{feedMapping.showEmptyFeedColumns}" value="Show Empty Columns (#{feedMapping.hiddenEmptyFeedMappingColumnCount} hidden)" rendered="#{! empty feedMapping.hiddenEmptyFeedMappingColumns}"/>
 <h:form id="mapping">
 <div style="float: left; width: 60%;">
 <rich:panel id="feedColumns">
 <f:facet name="header">Your Columns</f:facet>
 <rich:dataTable value="#{unmappedColumns}" var="fm"
 styleClass="datatable" rowClasses="rowOdd,rowEven" style="width: 100%;">
 <h:column>
 <f:facet name="header">Your Column</f:facet>
 #{fm.rawColumn.columnNumber}
 </h:column>
 <h:column>
 <f:facet name="header">Example Data(Drag me!)</f:facet>
 <a:outputPanel style="border:1px solid grey;padding:2px;"
 layout="block">
 <rich:dragSupport dragIndicator=":indicator" dragType="column"
 dragValue="#{fm.rawColumn.columnNumber}">
 <rich:dndParam name="label" value="#{fm.rawColumn.header}" />
 </rich:dragSupport>
 <span style="float: right"><strong>#{fm.rawColumn.header}</strong></span> <em>#{fm.rawColumn.oneExample}</em>
 </a:outputPanel>
 </h:column>
 </rich:dataTable>
 </rich:panel>
 </div>
 <div>
 <rich:panel id="cdmFields">
 <f:facet name="header">
 <h:outputText value="CDM Fields" />
 </f:facet>

 <rich:dataGrid value="#{remainingCdmFields}"
 var="fm" columns="2">
 <h:column>
 <a:outputPanel style="border:1px solid #{fm.required ? 'red' : 'grey'};padding:2px;" layout="block">
 <rich:dropSupport acceptedTypes="column" dropValue="#{fm.cdmField}"
 dropListener="#{feedMapping.mapColumn}" reRender="cdmFields,messages,mappedColumns,feedColumns">
 </rich:dropSupport>
 #{fm.cdmField.name}
 </a:outputPanel>
 </h:column>
 </rich:dataGrid>
 </rich:panel>
 </div>

In the SFSB the DnD event is received like this:

 public void mapColumn(DropEvent dropEvent) {
 Dropzone dropzone = (Dropzone) dropEvent.getComponent();
 this.mapColumn(Integer.parseInt(dropEvent.getDragValue().toString()), dropzone.getDropValue().toString());
 }

Hope that helps. You'll find quite a few Richfaces examples in the seam example apps - especially the wiki. Though they don't cover DnD.
