Hi,
Using Seam 1.2.1.GA + JBoss AS 4.0.5.GA, I have a xhtml page with a datatable.
The number of columns of this table is variable. I use a jstl <c:foreach> in
this datatable like this:
<h:form id="MyForm">
| ...
| <h:dataTable value="#{bean.var}" var="lineSimple">
| <h:column>
| <f:facet name="header">
| <h:outputText value="Activite" />
| </f:facet>
| <h:outputText value="#{lineSimple.lineDesignation}"/>
| </h:column>
|
| <c:forEach items="#{bean.var.columnDataModel.wrappedData}"
| var="columnSimple">
| <h:column>
| <f:facet name="header">
<h:outputText
value="#{columnSimple.columnDesignation}"/>
| </f:facet>
| <h:inputText
value="#{lineSimple.cellList[columnSimple.columnId].cellValue}"/>
| ...
| </c:forEach>
| ...
| </h:form>
All this is in a form with other inputs. My page uses a template with an Ajax
menu that is also in a form. When I change the values of my inputs, the number
of columns of the table increases. When I do it once it's ok but when I do it
again I have this error:
duplicate Id for a component MyForm:_id914:_id44
