[jboss-user] [JBoss Seam] - BUG <s:selectDate for=

[beligum]

Hi all,

I think I found a bug in the way s:selectDate is implemented, when acessed from facelets. I use this in a facelet-template:

  | <h:inputText id="#{id}" value="#{value}" styleClass="input" style="width: #{width};" disabled="true">
  | 	<a4j:support event="onblur" reRender="#{id}Error"/>
  | </h:inputText>
  | 
  | <s:selectDate for="${id}">
  | 	<a href="#"><h:graphicImage value="img/icons/16x16/calendar.gif" /></a>
  | </s:selectDate>
  | 

And the template is instantiated as follows:

  | <ui:decorate template="templates/t_form_calendar_entry.xhtml">
  | 	<ui:param name="id" value="jobStartDate" />
  | 	<ui:param name="label" value="#{msg.startDate}" />
  | 	<ui:param name="value" value="#{newJob.startDate}" />
  | 	<ui:param name="width" value="300px" />
  | </ui:decorate>
  | 

The "dynamic" ${id} in the selectDate throws an error:

Anyone else having this problem?
If I use a static id, everything works.
