Simple Jelly <f:dropdownList> prevents the build step from appearing

[Kirill]

Hi,

I have created a build step that contains a simple drop-down list that should provide different UI pieces depending on selection. Selection contains just 2 hard-coded items.

That's how I implemented it:

<f:dropdownList name="eventType" title="Event type">
    <f:dropdownListBlock title="Event as XML" value="eventXml">
        Event XML is selected
    </f:dropdownListBlock>
    <f:dropdownListBlock title="Event as Maven GAV" value="eventGav">
        Event GAV is selected
    </f:dropdownListBlock>
</f:dropdownList>

The sample text lines in blocks will be replaced by actual Jelly code - I wanted to start with something very simple. All I need is to get at this stage in my Builder is a String (eventXml or eventGav).

Appropriate Java code:

public class EventDispatcher extends Builder {

    ..............
    private String eventType;

    @DataBoundConstructor
    public BaselineDefinedMessageDispatcher(..............,
                                            final String eventType) {
        ..............
        this.eventType = eventType;
    }

    public String getEventType() {
        return eventType;
    }

    public void setEventType(String eventType) {
        this.eventType = eventType;
    }

    ..............
}

As soon as I added the mentioned Jelly block to my config.jelly...The build step is just not added to the job configuration any more! No errors or exceptions anywhere...
I browsed Jelly tags' docs (https://jenkins-ci.org/maven-site/jenkins-core/jelly-taglib-ref.html), but there are no instructions about how to bind this stuff in Java.
I installed the ui-samples-plugin, but there are uber-complicated samples...

Please tell me what am I doing wrong. Btw, is there any way to tell Jenkins to log all Jelly parsing and mapping errors?

Regards,
Kirill.

I think that you need to dive deeper into 

https://github.com/jenkinsci/ui-samples-plugin/blob/master/src/main/resources/jenkins/plugins/ui_samples/DropdownList/index.jelly

This is one of the most complex bindings, where you need to build separate classes for each block.
