p:dataTable with unknown number of columns

[MechanicalWolf]

Hello!
I`m trying to make a dataTable, in wich i don`t know the number of columns and rows.
I got a list dataFieldGroups, wich contains the rows - a list fieldValuesList
fieldValuesList contains a String field value
dataFields - is just a list of String names of columns

so i need the table like:
Column1 | Column2 | Column3 <- List<String> dataFields = {"Column1","Column2","Column3"}
------------------------------------------------
Value1.value |Value2.value|Value3.value <- List<FieldValue>fieldValuesList ={Value1,Value2,Value3}


And here is the code:

<p:dataTable value="#{directoryBean.dataFieldGroups}" var="fg" rowIndexVar="j">

<c:forEach items="#{fg.fieldValuesList}" var="fv" varStatus="i">
<p:column>
<f:facet name="header">
<h:outputText value="#{directoryBean.dataFields[i.count -1]}" />
</f:facet>
<h:outputText value="#{fv.value}" />
</p:column>
</c:forEach>
</p:dataTable>

the problem is, that nothing is displayed.. When i tryed the same with all List<String> it worked, but with objects - not

PF currently doesn't support dynamic columns in a data table (see, and maybe vote for, bug 491 - http://code.google.com/p/primefaces/iss ... ail?id=491). Hopefully this will be added for version 2.2 which is due out towards the end of the month.

thank you for info.
is there any chance to use Rich Faces dynamic table in Prime faces project?

Sure they are compatible libraries.

p:columns is coming soon in 2.2. release by the way, as this release will introduce the new datatable with tons of new features and enhancements.
