Error #1014: Class com.esri.viewer::BaseWidget could not be found

[Anonymous User]

Greetings All!

This might be a really trivial question but I wanted to take a compiled widget (in the form of a subdirectory containing an swf and xml file), add it to the widgets folder of the base flexviewer, then add the appropriate <widget> code to the config.xml file and that was all I needed to do to have a new widget added to my existing viewer. When I do this however I get the error message "Error #1014: Class com.esri.viewer::BaseWidget could not be found" ... Any ideas what I'm doing wrong or how to fix it?  The new widget works just fine in the application is was original compiled with ...

Was the widget compiled for Viewer 2.1? Are you trying to add it to a 2.2 Viewer?

That could cause it, huh? I'll check and let you know ...

Rafael,

   If you are using the Flex Viewer 2.2 and when you use a widget that was compiled for 2.1 you will get this error. You need to get a newer version of the widget you are attempting to load or if the source code for the widget is available you need to recompile it yourself to make it 2.2 compatable.

Robert,

You are fast!!! Thanks. But i edited my post with a question more objective. I guess that will be more easy for you.

Thanks!!!

Well, recompiling with version 2.2 certainly fixed the problem but I was just curious about the "plug and play" aspects of using precompiled widgets. Do you know if newer widgets are backward compatible, that is will work in an older viewer, or do you always need to be on a consistent build?

Rafael,

   BaseWidget is not part of the API it is part of the Flex Viewer which is built on the API.

Bob,

    Widgets had a minor change from 2.1 to 2.2 that will not allow compiled widgets to be backward compatible.
