Grails :: How To Override g Message Tag

1. Create a tab lib (grails-app/taglib)

2. Extend with ValidationTagLib

3. Example

package com.test.taglib

import org.codehaus.groovy.grails.plugins.web.taglib.ValidationTagLib

class MyCustomTagLib extends ValidationTagLib {
 static validationTagLibStatic = null

    static namespace = "g"

    Closure message = { attrs ->
        ValidationTagLib validationTagLib = validationTagLibStatic ?: (validationTagLibStatic = grailsAttributes.applicationContext.getBean('org.codehaus.groovy.grails.plugins.web.taglib.ValidationTagLib'))
        validationTagLib.message.call(attrs)
    }
}

Grails Add New Resources To MessageSource Dynamically

First create a groovy file with the following contents

package com.pkm.message.test

import grails.util.Environment
import javax.servlet.ServletContext

class MessageSourceCreator {
    public static def grailsApplication = null
    public static def servletContext = null
    public static def messageSource = null
    private static final String MESSAGE_FILE_DIR = "/WEB-INF/resources/messages"

    /**
     * @param fileName "some.message.properties"
     */
    public static void addNewMessageFile(String fileName) {
        String basePath = servletContext.getRealPath("/")
        fileName = fileName.substring(0, fileName.lastIndexOf("."))
        String relativeFilePath = "${MESSAGE_FILE_DIR}/${fileName}"

        if (Environment.isWarDeployed()) {
            messageSource.pluginBaseNames.add(0, relativeFilePath)
        } 
        else {
            String separator = Environment.current == Environment.TEST ? "/" : ""
            messageSource.pluginBaseNames.add(0, basePath + separator + relativeFilePath)
        }
    }

    public static void initialize(def ga, def sc, def ms) {
        grailsApplication = ga
        servletContext = sc
        messageSource = ms
    }
}

From BootStrap, need to call first initialize & then addNewMessageFile

/**
 * From BootStrap, need to call first initialize & then addNewMessageFile
 */
import com.pkm.message.test.MessageSourceCreator

class BootStrap {
    def grailsApplication
    def servletContext
    def messageSource

    def init = { servletContext ->
        MessageSourceCreator.initialize(grailsApplication, servletContext, messageSource)
        MessageSourceCreator.addNewMessageFile("some.message.properties")
    }

    def destroy = {

    }
}

Android: Update GUI field vlaue/display or show a message (toast) from Thread

Util Class

package com.pkm.android.utils.thread;

import android.app.Activity;
import android.content.Context;
import android.widget.Toast;

public class ThreadUtils {
    public static Object context = null;
    private static Activity activity;
 
    /**
     * setCurrentActivity(this) in onStart()  on each activity 
     * setCurrentActivity(this) in onResume()  on each activity
     * setCurrentActivity(null) in onPause()  on each activity 
     */
    public static void setCurrentActivity(Activity currentActivity) {
        activity = currentActivity;
    }

    public static Activity currentActivity() {
        return activity;
    }
 
    public static void message(final String message) {
        activity.runOnUiThread(new Runnable() {
            public void run() {
             Toast.makeText((Context) context, message, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

Example Usage

@Override
protected void onStart() {
    super.onStart();
    ThreadUtils.setCurrentActivity(this);
    ThreadUtils.context = getBaseContext();
}

ThreadUtils.message("A message from thread, will normally fail!!!");
