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.

    List Control , JSON data and Formview Control

    Hi,

    I'm using a List control with a Formview control as the detail view. I'm populating the list control with data from a client-side data cache using the method, "setListColumnsAndPopulate".

    I have configured a Formview control as the detail view on the List control. I have configured the data source in the List control as static and entered only the column headings as I need to do this so I can configure the Formview control.

    This seems to be working fine for the data I populate into the List control. I can click on a row in the List control, and the detail view (Formview control) is rendered with the data in the correct fields.

    However, if I try to create a new record, a blank new record appears (in the Formview control), but when I try to edit any of the fields, I get this error:
    "Unable to get property '*renderIndex' of undefined or null reference".

    I suspect the Formview control is not connecting properly with the data source in the List control. I've gone through all the related videos to do with client side data cache and list controls, but none of them seem to cover how to implement a detail view on the list control under the scenario of programatically populating the data in the list control. (previously I had this working using sql as the data source, but since my app needs to work off line, I'm switching to the client side data cache as the data source).

    Has anyone ever set this up ? Am I approaching this the right way? Any help appreciated.

    Thanks,
    Greg

    Re: List Control , JSON data and Formview Control

    Figured out what is causing the problem. I had added a filter to the List control. Not sure why, but the filter seems to be affecting the creation of new records in the Formview control.

    This is the filter I'm using: data.id_location == {dialog.object}.getValue('locations') which I have placed in the list properties filter field. It is filtering the list as per the value selected in the 'locations' dropdown. However, its having this strange effect on the creation of new records in the formview control which is setup as the detail view for the list control.

    Any ideas how I can fix the problem ? (I tried adding a default value to the id_location field of new records in the formview control to meet the filter criteria, but that didn't do it).

      There are a lot of settings involved here. You'd need to post your UX with a sample table.

        I'll need to email it as it's over 1M.

          Think I have solved this problem. When I am updating the fields in the formview , I'm committing the changes immediately back to the list using the onUpdate event in the field of the formview control. The field I'm filtering on in the list (id_location) has not been committed back to the list, so the list is 'filtering' out this new record.

          This is what is causing all the problems. I confirmed it by adding a 'Save' button so the full record (including the default field set for id_location) get committed back to the list in one go.
