Hi every one,

is there any way to conditionally display checkboxes, inputfields , text etc etc in the new Talend component kit? in xml one could use show_if...

Hello,
The annotation @ActiveIf is designed for this purpose.
Here is a quick example :

public class MyConfiguration {

 @Option
 private boolean requiredAuthentication;

 //you can show a username and password according to the value of requiredAuthentication
 @Option
 @ActivetIf( target = "requiredAuthentication", value = {"true"} )
 private String username;

 @Option
 @ActivetIf( target = "requiredAuthentication", value = {"true"} )
 @Credential
 private String password;

}

check the API javadoc for more details https://talend.github.io/component-runtime/apidocs/1.0.5/api/index.html

Hi anas,

Thanks for your reply, but the solution is a bit buggy . i added the annotations 100% like what you added but then to see the changes i will need to switch views i.e something is not refreshing in real time, is there any solution to this behavior?

Best regards

I suggest you to test with a newer version of the studio.
You can download the latest released version from here Talend Open Studio

Hi i m not using open studio, i m using Talend studio 7.0.1, we are tying to see if a component that was created with javajet can be implemented in component kit, The company will surely not be updating the version(7.0.1) of Talend we are using very soon, so it seems there is no workaround in our version ?

best regards

In this case, i strongly suggest you to open a bug in the project bugtracker so that the team can provide you the necessary support for your specific version.
