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.

    setValue() not working on New record

    My app needs to be able to go offline and still function.

    I have a list that has the primary key set as the return value. The primary key is one field which is a bigint in the database. This list is set to persist to local and has a detail view.

    I have used the Genie to generate the CRUD buttons and text boxes for the fields in the table. I click on the "New Record" button and fill in the fields that are needed for a new record and then I click the Save button. The new record shows up in the list with the blue triangle in the top right corner. This all works as expected.

    I have also added a textbox and a button to the UX. I'm entering a primary key value into the text box and clicking on the button which has this code in it's click event:

    Code:
    var value = {dialog.object}.getValue("txtTest");
    {dialog.object}.setValue("listTest",value);

    If I put in a primary key value for a record other than the record that I inserted, the record is selected in the list, as expected. The problem is that if I put in the value for the newly-inserted but not yet synchronized record, the record is not selected and the previous selection is de-selected leaving no records selected.

    How do I select a record from the list that has not yet been synchronized back to the server?

    I'm using build 12.3, 3200- 4560.

    Re: setValue() not working on New record

    Hi Bobby,

    .setValue won't work in this case because the list object property of the list data that is being used in the .setValue isn't the actual value of the key... yet. After the record is sync'd the property value used in .setValue is the key value, but before being sync'd it's a temporary value.

    So, because it's a temp value, we need to find out what that temp value is. Part of the problem here, though, is that the property used in .setValue is named *value... and that name is tough to work with. So, we need to change that property name and then find the temp key value to look for.

    Here's the code and video to get this done. This code works with multiple new, unsync'd rows. Excellent question.

    Code:
    var lObj = {dialog.Object}.getControl('LISTTEST');
    
    var value = {dialog.object}.getValue('EmployeeKey');
    //{dialog.object}.setValue()
    
    var inList = lObj.valueInList(value);
    var newValue;
    
    if(inList == false){
    
    	for(i=0;i<lObj._data.length;i++){
    		if(lObj._data[i].EmployeeId==value){
    			var _dataStr = JSON.stringify(lObj._data[i]);
    			var _newDataStr = _dataStr.replace('*value','keyValue');
    			var _dataObj = JSON.parse(_newDataStr);
    			newValue = _dataObj.keyValue;
    			lObj.setValue(newValue);
    			return;
    		}
    	}
    }else{
    	lObj.setValue(value);
    }

      You also want to use ' and not " e.g "txtTest" use 'txtTest' .. cheers Pete

        Either is fine. Pick one and try to stick with it. You may need to escape in some instances. JSON wants double quotes. Alpha handles either.

          Thanks, David. That was exactly my problem. The *value property was set to "" on the newly inserted but not yet sync'd record.

          Thanks a lot!

            Actually... the *value property is set to something like... "_temporaryValue_4C2B3680-D90D-49AE-95EE-E605DA1B71A8". Is it set to "" for you? If so, I don't think you'd be able to use .setValue.

              Yep, I'm sorry. It was set to something similar. I hit "post" to quickly on my last post. :O

                  Yep... really. Check your code. If you can't see your error, then run your code in Chrome and check your console log for the error. Fix it, then run it again. I believe you'll find that both single and double quotes work.

                    Bobby,

                    Here are 2 other methods for doing this. One is using .filter (which really just produces it's own loop). Another is using a loop, but using the value of the loop to establish the logical row. I'm not 100% sure of this one, but it's seems ok.

                    Also, instead of using *value, use *renderIndex, which is the logical row of the List. It's simpler.

                    Interesting stuff.

                    Code:
                    debugger;
                    var empKey = {dialog.object}.getValue('EmployeeKey');
                    var lObj = {dialog.Object}.getControl('LISTTEST');
                    
                    var inList = lObj.valueInList(empKey);
                    
                    if(inList == false){
                    
                    	var lData = lObj._rData;
                    	var empData = lData.filter(function( obj ) {
                    	  return obj.EmployeeId == empKey;
                    	});
                    
                    	var _dataStr = JSON.stringify(empData);
                    	var _newDataStr = _dataStr.replace("*renderIndex","__renderIndex");
                    	var _dataObj = JSON.parse(_newDataStr);
                    	var listRow = _dataObj[0].__renderIndex;
                    	lObj.setValue(listRow);
                    	return;
                    
                    }else{
                    	lObj.setValue(empKey);
                    }
                    Code:
                    var lObj = {dialog.Object}.getControl("LISTTEST");
                    
                    var value = {dialog.object}.getValue("EmployeeKey");
                    
                    var inList = lObj.valueInList(value);
                    var newValue;
                    
                    if(inList == false){
                    
                    	for(i=0;i<lObj._data.length;i++){
                    		if(lObj._data[i].EmployeeId==value){
                    			lObj.setValue(i);
                    			return;
                    		}
                    	}
                    }else{
                    	lObj.setValue(value);
                    }
