thanks for reply Jamie ... ok i just fig out the prob...
heres the change i made to my jwc:
<component id="tableStudentList" type="contrib:Table">
<inherited-binding name="source" parameter-name="ticketList"/>
<static-binding name="columns" value="student:Name:name" />
</component>
basically this ties in the passed params into the comp...i guess
BUT, i have a ques," is this how u ALWAYS bind parameters passed to a jwc
with the jwc's components? "
bascially i googled around and got over my error... but what is the
logic/explanation behind the inherited-binding / parameter-name properties?
yaay..finally i can submit my HW ;-)

pageBeginRender() is called before the components are rendered, so that
shouldn't be your problem.
can you paste up the code in your page's pageBeginRender() method?

Hi,
I am trying to create a component using the contrib:Table component.
Basically in my application, there is a student resultSet that I display
many number of times. Only the source of the contrib:Table keeps
changing and so I decided to make a StudentTable component, accepting a
list of students as a parameter. But I keep getting a runtime error:
org.apache.tapestry.ApplicationRuntimeException
Either the tableModel parameter or both source and columns parameters
must be specified by component StartPage/
stuentsRegisteredForCourses.tableStudentList.tableView
.jwc:
<parameter name="studentList" type="java.util.List" required="yes"/>
<property-specification name="student" type="edu.reg.hb.Student"/>
<component id="tableStudentList" type="contrib:Table">
<binding name="source" expression="studentList"/>
<static-binding name="columns" value="student:Name:name" />
</component>
.java has the respecitive getter/setter for studentList and student
-----
now trying to use this comp in a page:
.page:
<property-specification name="students" type="java.util.List"
persistent="yes"/>
<component id="stuentsRegisteredForCourses" type="TableStudentList">
<binding name="studentList" expression="students"/>
</component>
.html:
<table jwcid="stuentsRegisteredForCourses" />
---
i dont know when the component gets loaded, but i suspect that it gets
called before the pageBeginRender(), which actually sets the students
list with some value.
i cant fig out what am i doing wrong :(
Thanks,
-Dan
