Action fired twice on datalist action plugin

I'm implementing a datalist action plugin. I can compile the plugin and correctly load it using the plugin manager. However when I add it to a datalist and press the associated link the executeAction() function is executed twice. Why is it happening? Am I doing something wrong?

This is a link to the test application

This is a link to the jar of the plugin.

This is the code of the plugin (I kept it the more minimal as possible for the sake of clarity):

package org.joget.tutorial;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;

import org.joget.apps.app.service.AppPluginUtil;
import org.joget.apps.app.service.AppUtil;
import org.joget.apps.datalist.model.DataList;
import org.joget.apps.datalist.model.DataListActionDefault;
import org.joget.apps.datalist.model.DataListActionResult;
import org.joget.apps.form.service.FileUtil;
import org.joget.commons.util.LogUtil;

public class GenerateNewDocumentVersionDatalistAction extends DataListActionDefault {

    private final static String MESSAGE_PATH = "messages/GenerateNewDocumentVersionDatalistAction";
    private static int execution = 0;
    
    public DataListActionResult executeAction(DataList arg0, String[] arg1) {
            LogUtil.info("CollboartiveEditing - Plugin creating new document version", "Generating test document: run " + execution);
            execution++;
        return null;
    }
    
    public String getConfirmation() {
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getConfimation: " + getPropertyString("confirmation"));
        //return getPropertyString("confirmation"); //get confirmation from configured properties options
        return null;
    }

    public String getHref() {
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getHref: " + getPropertyString("href"));
        return getPropertyString("href"); //Let system to handle to post to the same page
        //return null;
    }

    public String getHrefColumn() {
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getHrefColumn: " + getPropertyString("recordIdColumn"));
        //return getPropertyString("hrefColumn"); //Let system to set the primary key column of the binder
        return null;
    }

    public String getHrefParam() {
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getHrefParam: " + getPropertyString("hrefParam"));
        //return getPropertyString("hrefParam");  //Let system to set the parameter to the checkbox name
        return null;
    }

    public String getLinkLabel() {
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getLinkLabel: " + getPropertyString("label"));
        return getPropertyString("label"); //get label from configured properties options
        //return null;
    }

    public String getTarget() {
        ////return "post";
        //LogUtil.info("Collaborative Editing - Generate new document version plugin", "getTarget: " + getPropertyString("target"));
        //return getPropertyString("target");
        return null;
    }

    public String getClassName() {
        return getClass().getName();
    }

    public String getLabel() {
        return AppPluginUtil.getMessage("org.joget.tutorial.GenerateNewDocumentVersionDatalistAction.pluginLabel", getClassName(), MESSAGE_PATH);
    }

    public String getPropertyOptions() {
        return AppUtil.readPluginResource(getClassName(), "/properties/generateNewDocumentVersionDatalisAction.json", null, true, MESSAGE_PATH);
    }

    public String getDescription() {
        return AppPluginUtil.getMessage("org.joget.tutorial.GenerateNewDocumentVersionDatalistAction.pluginDesc", getClassName(), MESSAGE_PATH);
    }

    public String getName() {
        return "New Document Generator Datalist Action";
    }

    public String getVersion() {
        return "5.0.0";
    }

}

When I click on the action link in the datalist in the log file I get the following output:

INFO  20 Nov 2017 14:55:01 CollboartiveEditing - Plugin creating new document version  - Generating test document: run 0
INFO  20 Nov 2017 14:55:01 CollboartiveEditing - Plugin creating new document version  - Generating test document: run 1
