I have a custom component, with a panel containing 3 buttons.
On button click, I would like to invoke database service which will query database.
But when I click it, the browser console gives me the error "nameofservice is not undefined"

Is there restriction that custom component cannot invoke service?

Hi,

This should work. Please check other actions, for example run JS:prealert("test event");/pre

Hi,

run javascript is running fine.
only fail on invoke database service.

I found that the service is not defined as other database service
code
/*
* Nonvisual components
*/
var datasources = [];

 getGames = new Appery.DataSource(WarehouseDB_GameList_list_service, { 
     'onComplete': function(jqXHR, textStatus) { 

         $t.refreshScreenFormElements("Home"); 
     }, 
     'onSuccess': function(data) {}, 
     'onError': function(jqXHR, textStatus, errorThrown) {}, 
     'responseMapping': [{ 
         'PATH': ['$'], 
         'ID': 'listitem_games', 
         'SET': [{ 

etc etc....
/code

Hi,

Anyway, I have workaround by defining the service myself, inspired by your thread here: https://getsatisfaction.com/apperyio/...

You may close this issue now.

Thank you for the update!
