Doc Text:	Cause: When making changes to some resources, service groups, and fence agents while not in expert mode, attributes that are able to be set via luci only in expert mode could be lost. Consequence: Some configuration parameters could be erroneously removed. Fix: luci no longer removes expert mode-only attributes when changes are made to resources, service groups, or fence devices while not in expert mode. Result: Configuration parameters are no longer erroneously removed.	Story Points:	---

Description Radek Steiger 2014-06-23 14:05:11 UTC

Description of problem:

The expert mode in luci preferences allows the admin to set up some extra parameters for various resources/services. When such options are set for NFS Server resource and either the expert mode is disabled or the admin clears his cookies, any subsequent submission of the resource/service form causes these extra attributes to be removed.

In expert mode, I've set the attributes like this:
<nfsserver name="myNFSserver" nfspath="/nfs/recovery/path" path="/my/path"/>

Then, I've disabled Expert mode in luci preferences and opened the resource config page again and hit the Apply button once again. The xml is reduced into this:
<nfsserver name="myNFSserver" path="/my/path"/>


Version-Release number of selected component (if applicable):
luci-0.26.0-49.el6


How reproducible:
Always


Steps to Reproduce:
1. Enable expert mode
2. Create a 'NFS Server' resource, set 'nfspath' attribute to some value
3. Disable expert mode
4. Go back to the said resource configuration
5. Submit the form without doing any changes


Actual results:
'nfspath' attribute gets removed from configuration.


Expected results:
All extra attributes should be kept in the configuration unaltered, even if they're not shown because of expert mode being disabled.
