component binding
Hello,
I have a component with a parameter "param".
I have defined an accessor method for this parameter: "public abstract Object getParam();".
My accessor method always returns null, but getBinding("param") returns the correct value.
Why is it so?
Thanks,
Norbi

Thanks for your help in anticipation!
Part of the .jwc file defining the parameter:
<parameter name="rink" type="package.Rink" direction="in" required="yes" />
Part of the .java file defining the getter method:
public abstract package.Rink getRink();
I think these two lines correspond to my question. No other code is involved
in handling the parameter, in other methods I only try to call getRink().
But getRink() always returns null, getBinding("rink").getObject() returns
the right value. This means that the getter method exisits, I get no
exceptions when I call it.
Although it seems to be not too important, but my code would be much cleaner
and shorter if I could use the getter method. I use Tapestry 3.0b3.
Br,
Norbi

You are probably using it in a listener.
Please define it as 'auto', rather than 'in' and see if it works.
Best regards,

The direction is defined as "in", but the getter returns null.

Tapestry will not automatically define the accessors for "custom"
parameters. You have to specify a direction for your parameter that is
other than "custom" if you want Tapestry to implement the accessors. If
you don't specify a direction, the default is "custom".
