Opposite Results in isDefined page code examples for Adobe ColdFusion 2023.

Opposite Results in isDefined code examples for Adobe ColdFusion 2023.

There are 3 code example sections in the isDefined page.

• Using IsDefined
• Scope Evaluation Order and Unscoped Variables
• Dot-notation Variable Names

Below each example I see an "Expected Result". When I click on the "RUN CODE" button for each code example, the Current Engine value is defaulted to Adobe ColdFusion 2023.

When I run the code for the second and third code examples the results are different than the "Expected Result". Switching to a different server, Adobe ColdFusion 2011 for example, will generate results that match the "Expected Result".

Dot-notation Variable Names

Adobe ColdFusion 2023

Is 'form.submit' defined?YES (local['form.submit'])
Is 'submit' defined? NO

Adobe ColdFusion 2021

Is 'form.submit' defined?YES (local['form.submit'])
Is 'submit' defined? YES (form.submit)

The reason for this is that CF2021 is running update 12 on trycf.com currently, which is not the latest version. I think the difference is due to the searchImplicitScope change in the recent CF update. Details here: https://www.petefreitag.com/blog/cf-searchimplicitscopes/

Thanks for pointing this out, we will have to update that example to note that the result now differs based on what version of CF you are using.
