creating jwc:101
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

Posted by Dan � <po...@hotmail.com>.
Yea interesting. But it worked ONLY when i changed the regular
binding/expression to inherited/parameter.
I think its necessary to pass in parameters this way. In 3.0, maybe this is
the mechanism Tapestry uses to determine if the values are to be looked up
via ognl (from the .java ) , ie using the regular binding/expression
mechanism, or if the values are lookup up/gotten from the parameters and NOT
the .java, ie via inherited/parameter mechnism.

The inherited binding is the way to pass through a parameter
unmodified. I'm not sure why your previous code didn't work though.
There may be a difference in the processing sequence between an
inherited binding and a regular one. (In 4.0 there is just
"binding".) I don't have my 3.0 source code open and at hand, or I'd
go diving to look at it.

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

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?
