Gang,
I can't find how to set up Selectors. Any pointers?
Case;
Cocoon Block.
ImageOpReader can be stacked with a set of ImageOperations, each defined as a
separate component, with its own configuration.
ImageOpReader is supposed to look up a ImageOperationSelector, which will be
selected by name.
I did;
<role name="org.apache.cocoon.reading.imageop.ImageOperationSelector"
shorthand="image-operation"
default-class="org.apache.cocoon.components.ExtendedComponentSelector"
>
<hint shorthand="scale"
class="org.apache.cocoon.reading.imageop.ScaleOperation"/>
<hint shorthand="convolve"
class="org.apache.cocoon.reading.imageop.ConvolveOperation"/>
</role>
in a .xroles file, and then have a
m_OperationSelector = (ComponentSelector) man.lookup( ImageOperation.ROLE +
"Selector" );
and later the
ImageOperation op = (ImageOperation) m_OperationSelector.select( type );
But I get the message
"UnnamedSelector: ComponentSelector could not find the component for hint
[scale] (key [scale])"
and a very 'inconclusive' stack trace.
What am I missing?
Cheers
Niclas
What else is there to it?
