I need dynamic number of columns. Richfaces supplies it with <rich:columns>
in richfaces 3.3.3-final but for Richfaces 4 they seem to recommend <c:forEach>
.
c:forEach
I can't get it to work properly.Since I can't depend on the var from the datatable I can't figure out how to feed <c:forEach>
with the correct list of columns. (Each row has their own values but headers are the same)
Basically the data I want to display is a list with rows of x size, each row has a list of column values with y size. But how can have <c:forEach>
tell the backing bean what row it's at so I can feed the correct columns?
ui/a4j:repeat
I dont want to reinvent the wheel because I need frozen columns and many other features. Creating the table html this way and use jQuery for other features have been considered. However this would be hopeless to maintain and to much work.
I also looked at constructing it from the backing bean creating children dynamically but I don't like that at all. This would have to be the last resort.
Using: Tomcat 7, servlet 3.0, JSF 2.1x - Mojarra, Richfaces 4.x
Update
Okay so I'm getting some results finally. However my headers don't show. The values show perfectly but not the headers. Some problem doing them with iteration or something perhaps?
<rich:dataTable value="#{controller.rows}"
var="row">
<c:forEach items="#{controller.columns}" var="column">
<rd:column id="name" width="250">
<f:facet name="header">
<h:outputText value="#{row.myArrayList[column].header}" />
</f:facet>
<h:inputText value="#{row.myArrayList[column].value}" disabled="#{row.myArrayList[column].open}"/>
</rd:column>
</c:forEach>
</rich:dataTable>
