prepare data for (myfaces) datalist...

[stephan opitz <st...@gmail.com>]

eg. in myfaces i tried to adopt the pagedSortTable to clay and shale...
in teh example there the data is prepared in the constructor...

i thought ok: as i learned in registration from mailreader...
while canging sides in my application: call a method and fill the bean
which will be called next...

PagedSortableCarList pagedSort= (PagedSortableCarList) getBean("pagedSort");

the fill it:

for (int i = 100; i < 200; i++)
{
	Object car = new SimpleCar(i, "Car Type " + i, (i % 2 == 0) ? "blue"
: "green");
	pagedSort.getCars().add(car);
}

throws null pointer - cannot add an element to the list :-/

PagedSortableCarList.java
SimpleCar.java
SortableList.java
these three files needed to built up the paged example list...

in clay-config.xml
	<component jsfid="collage:dataTable" extends="t:dataTable">
		<attributes>
			<set name="value" value="#{messages['logon.footer']}" />
			<set name="var" value="car" />
			<set name="value" value="#{pagedSort.cars}" />

the problem is that the list gets it data direct from the
PagedSortableCarList - no direct access to any bean with init()... or
other shale methods needed

any solution how i handle to fill data in a list which will be called
after from a datalist?

is it neccessary that all beans are extrends to baseviewcontroller?

or at generall how to manage:

fill such a list in the init method...
but if changing side, because pagedList ;-), the list data - get mybe
from session...

how handling should be...
