'Whole' row Drag & Drop in a datatable

[hugo.sayag]

Hello,

To explain the context, I have a few ordered data tables with embedded 'choose a line & up/down' functionnalities (screenshot...) that I'm trying to replace with a 'grab a row and drop it on another one' principle. I'm using Richfaces 3.3.3.

In the existing code, the column list is dynamic (bean.items), the existing code using a c:foreach I'm not willing to replace since it does the job. What I managed to do is to grab whatever cell of a row and drop it on whatever cell of another row to move the whole row by 'simply' adding drag and drop support to the rich:column and passing the indexes of the dragged row and of the dropped row to my bean :

<rich:dataTable id="mytable" var="element" value="#{mylist}" rendered="#{not empty list}" rowKeyVar="row" >           

<c:forEach items="#{bean.items}" var="item">

<rich:column>

<rich:dropSupport acceptedTypes="int" dropListener="#{bean.processDrop}" reRender="table" dropValue="#{row}" />

<rich:dragSupport dragType="int" dragValue="#{row}"/>                                                

<f:facet name="header" align="center">

<h:outputText value="#{item}" />

</f:facet>

<h:outputText value="#{bean.getColumnValue(element,item)}"/>

</rich:column>     

</c:forEach>

</rich:dataTable>

What I don't like with that solution is that I've got as many dropzones as I have cells which is quite ridiculous since I'm moving a row.

Is there any way to implement a row wrapper 'between the rich:dataTable and the rich:column ??
