Tapestry[5] - Select Drop Down in a Grid Component

Hi Everyone,

I tried to override the jobClass row in a grid to display as a select drop
down.The following fragment code were used. 

<t:Grid  t:source="employeeList" t:row="employee"  t:model="employeeModel" >
       <t:parameter name="jobClassCell">
		 <select t:model="jobClasses" t:value="employee.jobClass"
t:context="employee.id"/>	
	</t:parameter>
</t:Grid>

It is not working! My guess is there might be a conflict between the two
models (employeeModel, which is a BeanModel, and jobClasses model, which is 
a SelectModel).

Any help?

Thank you.

It is working usign the following fragment code. It is to much code for
tapestry. If you have any way of doing this, Using the SelectModel object. 

Now the jobClasses is a list of a string,

public List<String> getJobClasses() {
	return employeeDao.getJobClasses();
}

public boolean getSelectedJobClass() {
         return jobClass.equals(employee.getJobClass());
}

<t:parameter name="jobClassCell">
	<select t:value="employee.jobClass" t:context="employee.id">	
		<t:loop t:source="jobClasses" t:value="jobClass">
			<t:if t:test="selectedJobClass">
				<option value="${jobClass}" selected="selected">${jobClass}</option>
				<t:parameter name="else">
					<option value="${jobClass}">${jobClass}</option>
				</t:parameter>
			</t:if>
		</t:loop>
	</select>
</t:parameter>

Thank you,

Anteneh

Thanks Thiago,

jobClass is a string object which I declare and generate the getter and
setter methods on my page to iterate through the jobClasses list and provide
the options for drop down.

private String jobClass;

For the first case Exception was not happened, A blank value and blank list
on the select drop down was displayed. 

Thanks again!

How exactly is it not working? Some exception? The dropdown is not
being rendered with the appropriate value? In this last case, does
your JobClass overrides the equals() method? If not, implement it and
now your first code will work.
