Question

I am trying to edit an already existing Flex project, and I see a warning on the line
“import com.Adobe.utils.StringUtil;” and the warning it shows is

Multiple markers at this line:
-mx
-The import utils could not be found.
-The import StringUtil could not be found.

so what could be the problem?

Well I was wondering what is the difference between import com.Adobe.utils.StringUtil; and import mx.utils.StringUtil;

Answer 1

com.adobe.utils.StringUtil and mx.utils.StringUtil are different classes. From the manual of mx.utils.StringUtil:

The StringUtil utility class is an all-static class with methods for working with String objects within Flex.

Mark that within Flex part.

And com.adobe.utils.StringUtil is part of Adobe’s as3corelib which is a pure AS3 library and offers different methods. You need to add the as3corelib’s StringUtil to remove the warning.
