I have a button on InfoWindow. and ClickEvent doesn't work. I think it because of infowindow doesn't attach this button to DOM correctly. I've made a wraper whis fake panel and now it works ok.

John99,

Which event on InfoWindow is not working for you. There are five handlers exposed to GWT from the 5 handlers documented for InfoWindow in the GMaps API. Please elaborate.

Sincerely,

Joseph
