Ok, let me describe my problem in a bit more detail via an analogy.
Let's say I have a html table, called ComputerPartTable, in a file -
ComputerPart. This table
has the following columns : partID, partName,partDesc. Now the user
can click on the partID column and that will forward them to another page,
ComputerPartDetails, that displays the details of the selected computer
part.
Now, each part has different attributes. CPU has clockspeed, fsb speed, etc.
RAM has size, speed, etc.
Ok, so I have created a custom component, called CPUComponentPart.jwc that
lists the relevant details of a CPU component. But what I want to do is, I
want to pass
the partID to the CPUComponentPart.java so that I can lookup the correct
details of
the selected part.
So in my ComputerPart I have
@Parameter
public abstract CPUComponentPart getCPUComponentPart();
public void onFormAction(Integer partID) {
getCPUComponentPart().setPartID(partID); // this is the line where i am
getting an exception
}
Hope that helps,
