New issue 1766 by [email protected]: Google Visualization taming URL
rewriter fails
http://code.google.com/p/google-caja/issues/detail?id=1766
Google Visualization taming, at rewriteDataSourceUrl():
https://code.google.com/p/google-caja/source/browse/trunk/src/com/google/caja/apitaming/google.visualization.policyFactory.js?r=5218#84
calls frame.rewriteUri() from the host frame, passing a host object through
the taming membrane. But frame.rewriteUri() expects to be called from guest
code. It tries to un-tame the object it's been given, realizes that this is
a host frame object, and panics (as well it should). The errors on the
console look like:
Rejecting url
http://spreadsheets.google.com/tq?key=pCQbetd-CptGXxxQIG7VFIQ&pub=1 because
TypeError: Host object leaked without being tamed
ses-single-frame.js?debug=1:15879
Event handler threw: TypeError {} caja.js:189
The fix is to do something more clever in the rewriteDataSourceUrl()
function. Note that this function is *always* resident in the host frame,
due to the fact that the code it is a part of is coresident with the feral
Google JS API.
