[flexcoders] Re: Namespace declaration problem
It is not uncommon for someone to code something that requires someone else's code but they can't (or won't) include that code because they don't want to go through any licensing. They should have told you that it was required and where to go and get it. Was there ANY documentation to that effect? --- In flexcoders@yahoogroups.com, brucewhealton br...@... wrote: I thought, when I first read this, that you were saying that it is a part of a normal flex installation.

Can anyone help me make sense of this, please? Bruce

[flexcoders] Re: Namespace declaration problem
Bruce I'll see if I can explain it. The xmlns (XML Namespace) is used by mxml to state where component(s) are located. It is basically the same as using an import statement in Actionscript. In the namespace (Or import statement) think of the dots as directory (or folder) delimiters. So, in your case, in the src folder there would be a com folder. In that folder will be a adobe folder. In that folder will be a flex folder. In that folder will be a extras folder. In that folder will be a controls folder. In that folder will be a component named AutoComplete. Now, you could actually have this in your own source or it could be set up in a SWC in the libs directory. If you don't have the SWC then Flex will look for the specific directory structure as above. If both are missing then you will get this error. --- In flexcoders@yahoogroups.com, brucewhealton br...@... wrote: Hello all, I have this code that I copied from a text book on Flex.

[flexcoders] Re: Namespace declaration problem
Ok, thanks. Someone was saying that this was part of a flex installation. So, maybe I need to go into the library definition and somehow add this folder. I have used package definitions like this but when the text I was following didn't have this particular folder structure. I'll try to add this in the libraries section and if that doesn't work I'll write to the author of the text to see if he left out something from the code.
