Following test from the Liveconnect testsuite is failing due to this bug:
LiveConnect/JSListTest
Comments
EVALUATION The exception is caused by JSListTest.html line 31, app.setString("List entry: "+childElem()); By changing the line to following fix the problem. app.setString("List entry: "+childElem); I would imagine the right code should be either childElem.toString() or just childElem, but not childElem(). However, I am not sure why this is a regression.
