The following two issues are really close related to each other, so I'm reporting them here together. If they should be reported separately, then please indicate so, and I'll separate them.
I was trying to set custom value editor for some attributes (vacationInfo octet stream) when I discovered that the settings are ignored. I added a new entry into Value Editors (Eclipse Preferences -> LDAP Browser -> Value Editors):
value editor: "Text Editor"
Applied the settings (even restarted Eclipse) but on double clicking a vacationInfo attribute nothing happens, not even if I right click and select "Edit Value". The only way to edit the attribute value is to right click the attribute, select "Edit Value With" and there selecting "Hex Editor".
While I was messing with these settings I noticed that the "Edit Value With" submenu contains a changing entry (top one, besides the alternative editors and the "Preferences..." one) which as I found out is the entry corresponding to the previously selected attribute. So if selecting a password, afterwards selecting a string attribute and then looking into the "Edit Value With" submenu, it will contain a "Password Editor" entry which will do nothing. And sometimes it does really weird things.
Selecting a Boolean and afterwards a Password: the "Boolean Editor" entry is displayed but it opens the "Password Editor".
