• Type: Bug
• Status: Open
• Priority: Major

• Affects Version/s: Adobe Flex SDK Previous
• Component/s: .Unspecified - Compiler, Compiler API, MXML Compiler, MXML Compiler - Error Reporting, MXML Scripting
• Environment: Affected OS(s): Windows; Affected OS(s): Windows; Language Found: English

Description

Steps to reproduce:
1. Create an application MXML file with code behind (e.g. sample.mxml with sample.as)
2. Within a method of the sample.as, such as an initialization or button event add the following:

strTest = "sample";

// ... some code
// add a listener to some object or read an application parameter

var strTest:String = "aaa";

3. Compile code from comandline.

Actual Results:

Compiles with no issues.

Expected Results:

Should NOT compile and provide a variable declaration error for the line containing:

strTest = "sample";

Workaround (if any):

Be very carefull when programming with variables... this is a must fix for any real compilers (C++, .NET and Java would not compile).
