if i revert rev. 1640155 saving works again.
the problem seems to be this code:
{code:java}
// remove the properties that are not specified in the request
for ( Enumeration e = props.keys(); e.hasMoreElements(); )
{
final Object key = e.nextElement();
if ( !propsToKeep.contains(key) )
{
props.remove(key);
}
}
{code}
> Web Console Configuration plugin is confusing about default values &
> optionality of elements

> Key: FELIX-4677
> URL: https://issues.apache.org/jira/browse/FELIX-4677
> Project: Felix
> Issue Type: Improvement
> Components: Web Console
> Affects Versions: webconsole-4.2.2
> Reporter: Valentin Valchev
> Assignee: Valentin Valchev
> Attachments: FELIX-4677.jpg, FELIX-4677.patch
>
>
> Currently if you have an empty configuration with metatype, then when the
> editor is open, the default values from metatype are filled in.
> However, the user cannot determine if the configuration value is set or
> coming from metatype.
> So there should be an indicator, that the value is the *default* and is not
> actually stored in the configuration.
> There is also problem with optionality of the elements. In case there is an
> optional property, there is no way the user to set all other properties, but
> a selected, optional property.
> So there should be some checkboxes allowing the user to select which
> properties to save, and which not.
