hari commented on WW-4307:
--------------------------
<s:form method="post" action="saveCustomer" cssClass="well form-vertical" >
<h4> Create/Edit of
Customer</h4>
<div class="span5">
<s:hidden value="%{customerId}"
name="customer.customerId" />
<s:combobox
label="Beat Name"
name="beatName"
headerValue="--- Please Select ---"
headerKey="1"
list="beatNames" />
<s:submit value="%{getText('save')}"
cssClass="btn btn-primary"/>
</div>
</s:form>
The above is the snippet. The population of combobox works fine but the other
components are not displayed. list "beatNames" is populated from my action
class.
I tried with simple just s:combobox and too is giving this FreeMarker template
error!
