Re: [Fwd: Help needed to run widgets in other contexts] - smallwiki

Yes, the code I gave you at that time won't work in Seaside 2.8.  
WARenderLoop has been completely rewritten to avoid the need to store  
many unnecessary continuations. This greatly reduces the memory  
requirements per session.

What I suggest to do is that you implement a decoration that you can  
add around your component. Inside this decoration you store the  
context-holder and wrap the rendering and callback processing into

	PRCurrentContext use: contextHolder during: [ ... ]

 Help!

 Hi All,

 A while ago Lukas gave me the following code for opening a pier widget
 so that it would be able to access its context even though we are not
 even in a pier application!

 self - is my control panel which runs in the WADispatcherEditor's  
 session.
 widget is PUUsers or PUGroups

 ControlPanel-callWidget: widget  titled: title

     PRCurrentContext use: self during: [
         WARenderLoop new call: (widget
             addDecoration: (WAWindowDecoration new
                 title: title;
                 yourself);
             yourself) ]

 This works to the extent that the widget displays correctly,  
 however the
 buttons do not work due to PRCurrentContext value being nil.

 I am using the latest everything in the development universes.

 Does anyone have any ideas?

 thanks in advance

 Keith
