predicate property

[samuel786431]

I need to filter the extensions of files inside a pathfield.
the right way is the predicate.

import org.apache.jackrabbit.commons.predicate.Predicate;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Service;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Component
@Service
@Property(name = "PredicateVideo", value = "PredicateVideo")
public class PredicateVideo implements Predicate {
protected final Logger log = LoggerFactory.getLogger(this.getClass());

public boolean evaluate(Object obj) {
    log.info("test "+obj.toString());
    return true;
}

}

I have a pathfield with the property predicate equal to PredicateVideo and when i run the page i can see inside the log:

Unable to retrieve the predicate PredicateVideo

Why?

Thanks

Hi 

Please go through the documentation of "CQ.form.PathField",

Link:- https://docs.adobe.com/docs/en/cq/5-6/widgets-api/index.html?class=CQ.form.PathField

regex :

linkPattern : String

1.  
2. regex :/\.(png|jpg|jpeg)$/,
3. regexText : "Please choose an correct file"

Or you would need to write custom pathfield, 

Pathfield has a property called predicate which can be used for filtering. You can create and register a custom predicate that returns false for the paths you don't want to be visible in the the dialog. The name of the custom predicate can then be passed to the config of pathfield.

You can find information here : http://wemcode.wemblog.com/custom-predicate-for-pathfield

I hope this would help you.
