The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Ext JS Issue, Date field showing NaN/NaN/NaN

Asked by danfiggolf in Asynchronous Javascript and XML (AJAX), JavaScript, JavaScript Frameworks

Tags: ext js, grid, javascript, CRUD store, date field

I have a setup that follows the Ext.data.DataWriter Example on the Ext JS site, with the exception that I didn't extend any classes. The create, update, read, destroy is all working perfectly fine with the grid. All the columns are working perfectly fine except for the date column. What happens is when the grid loads the data and is first rendered, all the columns are read in like they should be except for the date column. The date column all read NaN/NaN/NaN, and the data is coming in fine from the json source as can be seen from Firebug.

Anyways, the date field editor is working just fine as I can set a date, save the record, and it goes into the database just fine (I doublechecked in phpmyadmin). I have a feeling the issue might have to do with the format of the date data, which is saved/loaded like this: "2009-09-02T00:00:00"

I will attach a screenshot of what it looks like and my code.
