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!

Coldfusion 8 Upgrade - CFC's & Application Settings & Mappings

Asked by AaronDitto in Cold Fusion Markup Language, ColdFusion Application Server, ColdFusion Studio

Tags: , ,

I have just finished upgrading our entire Intranet application to CF8. The upgrade went well, and all is working as it should. However, I've recently started diving into some of the new Ajax capabilities that have been introduced (updated) into CF8, and have run into a wall trying to get simple bind & cfc returns to work correctly.

Our existing CFC's work perfectly fine, and we have several. They are being defined within the Application.cfm , however I think the issue is that mappings, application.cfm, and CFC's were all written way back with CF6 was released, and they haven't been updated since.

I'm trying to get a simple cfgrid to pull from a data source (have tried our own SQL server, as well as cfartgallery, cfdocexamples, etc) to no avail. At first I thought it was just me not understanding binding and the appropriate arguments. But after pulling my hair out for days, I decided to load other peoples examples in our environment, and noticed those are not working either.

To end this novel, attached is the test CFM file, and the corresponding CFC (pulled from a forta tutorial I believe). It displays a simple HTML CFGRID, binded to the appropriate datasouce. In IE7 I recieve a "exception thrown and not caught" error, and in Firefox, nothing. The page just finishes loading, and displays nothing.

I think I need direction in what a normal Application.cfm file needs to look like to handle all of the necessary CF8 scripts etc, any mappings that might need to be added, as well as a quick description of binding and location for CFC's. I can provide additional examples of our existing settings upon request.

I'm giving this question a large point value as I'm desperately needing to finish a project by next week which includes the CFGRID, Flash Form and Binding examples.

Thanks,
Aaron Ditto
