After updating to Knime 2.8.1 I have problems installing the InfoCom JChem extensions.
I manually added the InfoCom update site to the Available Software Site in Knime. No problem so far. Upon pressing the 'Reload' button I get the following error instead of the password pop up I previously got in for example Knime 2.7:
Unable to read repository at https://www.infocom.co.jp/bio/knime/update/2.6/content.xml.
Unable to read repository at https://www.infocom.co.jp/bio/knime/update/2.6/content.xml.
No password provided.
I am running Mac OS X 10.8.4, with Java Version 7 Update 25 (build 1.7.0_25-b15).
In addition: after updating the infocom nodes from the 2.7 infocom repository in knime 2.8.1 or 2.8.2 on a mac all nodes have disapeared. Nowhere to be found. The whole Chemaxon tree is gone in the node-browser. The only fix seems to be to remove all Chemaxon/infocom add ons from knime, and reinstall the old nodes from the 2.6 repository.
This problem does not seem to occur on knime 2.8.2 running on linux (centos 6.2)
