I am getting below errors while trying to display zul files, this error occurs on allmost all browsers
TypeError: Cannot read property 'offsetHeight' of null
Failed to mount: Cannot read property 'offsetHeight' of null
TypeError: ao is null
in zk.wpd script file
Most of the times it works properly but only sometimes i get this error, i am not able to determine what is the root cause for it, will really appriciate if someone can point me to right direction to solve this issue.
I am using 6.5.2
which zk version do you use?

echarish ( 2015-03-16 07:58:48 +0800 )edittry adding logging for the result of the DB and otherwise classoverride the closest class where the exception is thrown and add logging there
chillworld ( 2015-03-16 08:21:35 +0800 )editin zk.wpd it is throwing zk.mounting = false; zk.error("Failed to mount: "+(e.message||e)); how can i check which component its not able to mount, is there a way to override zk.wpd file from application and log the component name in console or logger
