> There is a link to RF-11950.
> We got the message "element is null" when we send a click event for closing a tab. To retrieve the id of the close button (an image), we use the function getElementById (because of RF-11950). The click function calls a javascript function declared by a4j:jsFunction (see index.hxtml file - close task).
> This is the only information we have from firebug. When we close the tab directly by clicking on the close button/image, it works perfectly.
> *Note :* Moreover, there is also a strange behavior related to generated id on close button/image. When we specified a fix id on the h:graphicImage, the first id is correct but there is no id on other close button/image from other tabs!???. Having a fix id should trigger a duplicate ID but as the ids are not generated on other tabs, it does not.
