I have changed the onClick line to :
<x-tad-bigger><input type="submit" name="prev" value="Back" onClick="document.forms[0].action='${cocoon.continuation.previousBookmark.id}.kont';document.forms[0].submit()"/>
I am not getting the error message anymore, but also I am not getting a value for previousBookmark.id. what do I need o do to get this value? Do I need to set a parameter just before the sendPageAndWait. I saw an example in the samples which said the following:
var bkm = cocoon.createWebContinuation();
cocoon.sendPageAndWait("uri", {bookmark : bkm});
In my jx file I then did:
${bookmark.id}.kont
This returned a value, but when I hit the submit button the user is not re-directed back to the previous page. What am I not doing right here?
many thanks
Amdrew

<x-tad-bigger>Ok,
i'm completely lost with this one. I have a line of code which should take me back to the page I have just come from:
<input type="submit" name="prev" value="Back" onClick="document.forms[0].action='#{$cocoon/continuation/previousBookmark/id}.continue';document.forms[0].submit()"/>
but when the page loads I get the follwoing error message, why?:
