Hi Adam, Try including the <script> tag referencing the tweetgrid widget in your host HTML page directly. The reason why this won't work if you insert the <script> tag through an HTML widget is because GWT application load up in their own iframes. This means that references to variables that aren't properly scoped in a third party library (or in your own handwritten JavaScript code) might not be properly resolved since the window object would now refer to the <iframe> window rather than the main window.
Placing the <script> tag in your host HTML page should solve this problem. If you want to interact with the embedded widget from within your GWT code (through JavaScript Native Interface methods, a.k.a. JSNI), you can do this by referring to the objects defined on the main window through the $wnd handle. You can find more documentation on using JSNI at the link below: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideJavaScriptNativeInterface Hope that helps, -Sumit Chandel On Tue, Jan 27, 2009 at 1:32 PM, adambossy <adambo...@gmail.com> wrote: > > It just occurred to me that this pretty obviously won't work, because > it is calling the <script src="..."></script> widget tag inside of an > existing <script></script> enclosure.
