Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • run ajax callback conditionally

    In a UX repeating section, in the change event of a control I am running a action JS Ajax callback "populate controls in an unbound component ....."
    I, now would like to run the JS action only if it has not runned before for that record.

    I tried this changing the JS action into text mode, and set the IF condition, with NO results:

    var row = {dialog.Object}.getRepeatingSectionActiveRow('REPEATINGSECTION_1');
    var cl={dialog.object}.getValue('CALORIAS:row'); if this control wich is unbound is not null than I run the JS action

    if (!cl){

    // THIS IS THE START OF THE JS AJAX CALLBACK IN TEXT MODE
    var data = {dialog.object}.getValue('LIST::ALIMENTO::ALIMENTOID');
    if(typeof data == 'undefined') data = '';
    var _jsonCallbackData = '_callbackdata=' +$u.o.toJSON({_xbfunction: 'UNBOUND_UX_POPULATE_5e64809e68ba400e972fa505cd2bc391',_primaryKeyValue: data});
    {dialog.object}._lockPopulateControlsFromTable = true;
    {dialog.object}.ajaxCallback('','','system:UnboundUXPopulate','',_jsonCallbackData);
    //// THIS IS THE END OF THE JS AJAX CALLBACK IN TEXT MODE

    }
    any clues ?

    1. You need to add the row number to getValue using the + operator. row is a variable. 'row', with quotes around it, is a string:
    Code:
    var cl = {dialog.object}.getValue('CALORIAS:'+row);
    2. If you want your code to execute when cl is not NULL, then you need to change your if condition to just if (cl). A test for !cl will only be true when cl is null (or zero, or an empty string, or false, or undefined):
    Code:
    if (cl) {
    Hope that gets you started.

      Re: run ajax callback conditionally

      Thanks for your answer Sarah

      I do get into the if condition, but the JS action in text mode doesnt populate any records. I noticed that the variable "data" returs a string instead of an integer number as it should since this is the the primary key field in the table where to populate data from., so I changed it into a number, but still with no results

      Code:
      var row = {dialog.Object}.getRepeatingSectionActiveRow('REPEATINGSECTION_1');
      var cl = {dialog.object}.getValue('CALORIAS:'+row);
      
      if (!cl){
      
      
      // THIS IS THE START OF THE  JS AJAX CALLBACK IN TEXT MODE
      var data = {dialog.object}.getValue('LIST::ALIMENTO::ALIMENTOID');
      if(typeof data == 'undefined') data = '';
      if(typeof data == 'string') data = parseInt(data); [COLOR="#FF0000"]since it returs a string I changed it into a number[/COLOR]
      
      var _jsonCallbackData = '_callbackdata=' +$u.o.toJSON({_xbfunction: 'UNBOUND_UX_POPULATE_5e64809e68ba400e972fa505cd2bc391',_primaryKeyValue: data});
      {dialog.object}._lockPopulateControlsFromTable = true;
      {dialog.object}.ajaxCallback('','','system:UnboundUXPopulate','',_jsonCallbackData);
      //// THIS IS THE END OF THE  JS AJAX CALLBACK IN TEXT MODE
      
      }
      Could somebody point me the way ?

        I was able to have it done like this :

        Code:
        var row = {dialog.Object}.getRepeatingSectionActiveRow('REPEATINGSECTION_1');
        var cl = {dialog.object}.getValue('CALORIAS:'+row);
        
          if (!cl){
             {dialog.object}.runAction('populate data'); [COLOR="#FF0000"]'populate data' is the name of the javascript action[/COLOR]
          }

          This looks much cleaner! Very nice. :D
