Hi All,
I am having a little problem with datatable and binding.
Here is the code:
<t:dataTable id="dayParts"
value="#{targetingParam.cmpTargetDayParts}"
var="dayPart" cellpadding="0" cellspacing="0"
rowIndexVar="rowIndex">
<t:column style="height:30px" rendered="#{!dayPart.deleted}">
<h:selectOneMenu value="#{dayPart.startHour}"
onchange="updateTargetingActivity(#{rowIndexParam});"
id="hourFrom" styleClass="mform"
style="width:75px;" converter="ByteConverter">
<f:selectItems value="#{cmp_targeting.dayPartHoursFrom}"/>
</h:selectOneMenu>
<div>
<h:message for="dayParts" errorClass="error_message" />
</div>
</t:column>
</t:dataTable>
It works all fine, and I see a table with values on the screen. Now, when I
add binding to the dropdown:
binding="#{dayPart.htmlSelectOneMenuDaypartFrom}"
I get the following exception:
org.apache.jasper.el.JspPropertyNotFoundException:
/cmp_targeting.jsp(593,12) '#{dayPart.htmlSelectOneMenuDaypartFrom}' Target
Unreachable, identifier 'dayPart' resolved to null

In the bean I have the following code:
private transient HtmlSelectOneMenu htmlSelectOneMenuDaypartFrom;
public HtmlSelectOneMenu getHtmlSelectOneMenuDaypartFrom()
{
return htmlSelectOneMenuDaypartFrom;
}
public void setHtmlSelectOneMenuDaypartFrom(HtmlSelectOneMenu
htmlSelectOneMenuDaypartFrom)
{
this.htmlSelectOneMenuDaypartFrom = htmlSelectOneMenuDaypartFrom;
}
Does anyone has any clue?
Thanks,
Guy.
