<$button popup="$:/SamplePopupState!!editmode">Pop me up!</$button> <$reveal type="popup" stateTitle="$:/SamplePopupState" stateField="editmode"> <div class="tc-drop-down tc-popup-keep"> ! This is the popup And this is some text </div> </$reveal> and you'll get Internal JavaScript Error > Well, this is embarrassing. It is recommended that you restart TiddlyWiki > by refreshing your browser > > TypeError: undefined is not an object (evaluating > 'this.wiki.getTiddler(this.stateTitle).getFieldString') > > I simply wanted the popup to have its state stored in a field of an existing tiddler. In the popup I want to enter some data. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
