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.

  • How to insert row number when adding a new detail view of a disconnected list? NaN error


    Through a hierarchical menu system designed from a nested list, specific actions are run for every menu item. (Refer to Displaying Hierarchical Data in a List videos)
    In one action, I've been trying to add a new detail view record in the disconnected list and assign the value 'Header' to the control fieldtype & the value of the nested row number in the list to that new detail view record's FieldOrder control. I tried different scenarios. The thought process was that when a new record is inserted, it is then automatically selected, hence the selection[0]+1 would give me the actual row number but it doesn't; this following code when run, it inserts the fieldtype to the new record but gives me a NaN (not a number) for rowNum!

    if (action == 'action_1') {
    var lObjj = {dialog.object}.getControl('LIST_A');
    var rowNum = Number(lObjj.selection[0])+1;
    From my understanding, I though that the code for grabbing the row number is run before the new detail view was added for some reason, so I tried the A5.executeThisThenThat(1stFunction,2ndFunction,3rdFunction) and got the same error and behavior!

    Then I tried to assign the value of the renderIndex (plus one) to the rowNumber by following David's solution in this post but I received the error that _dataObj[0] is undefined. In the debugger, it shows that there is no new detail view record that was added at the first place when that code is run although it is set to run synchronously after the function that creates a new detail view (only the two objects that are already pushed in the server exist.)

    How do I set the value of FieldOrder of the newly added detail view of a disconnected list from an action that resides in another list acting as a hierarchical menu?

    Any ideas on why this is happening would be much appreciated.

    Thank you

    Never mind, I got it to work this morning after a good night sleep ^^

    Instead of using selection[0] of the not yet selected row to set the row number, I substituted with this:

    var rowNum = 1 + lObjj._data.length;
