Description Florian Best

When opening the Portal I get a javascript traceback:

TypeError: Cannot read property 'appendChild' of null
    at Object.l.place (dojo.js.uncompressed.js:13024)
    at Object._renderLink (dialog.js:139)
    at Object._addLinkFromUcr (dialog.js:104)
    at Object._addDefaultLinks (dialog.js:124)
    at Object.renderLoginDialog (dialog.js:108)
    at Object.callback (saml-config.js:11)
    at config.js:149
    at d (dojo.js.uncompressed.js:6076)
    at Array.then.c.then (dojo.js.uncompressed.js:6297)
    at callback (config.js:145) "TypeError: Cannot read property 'appendChild' of null

The only configured UCR variables are:
umc/login/links/how_do_i_login/enabled: true
umc/login/links/login_without_sso/enabled: true
umc/login/links/login_without_sso/text/de: Ohne Single Sign-On anmelden
umc/login/links/login_without_sso/text: Login without Single Sign On

As this is not the default configuration: can you add more information what changes you made on the system?

Just tested this.
It happened to me with a fresh system (master) without changing the default configuration, when opening the login field with SSO. 
Only once though, after a refresh I couldn't reproduce the error any more.

mhm.... if this traceback is the default for all installations, we should have a very high priority. If not, not...

Nico, can you track this?
