Item11402: Problem saving topic when SolrPlugin is enabled

I am having issue saving topic when SolrPlugin is enabled. The error i get is as follows.

Can't use string ("HASH(0x2a861f0)") as a HASH ref while "strict refs" in use

The problem happens when "EnableOnSaveUpdates" parameter is true.

Try to run configure and save changes. This will create the $Foswiki::cfg{SolrPlugin}{SupportedLanguages} hash automatically.

I will make the code more robust in case this hash isn't there.

The problem is Config.spec using type *STRING* rather than *PERL*

Hi Michael,

The github branch I linked to has configure checkers for SolrStartCmd, SupportedLanguages, SolrHome - it will try to guess the setting correctly (on a fresh install), and will detect a b0rked {SolrPlugin}{SupportedLanguages} config and will guess as defaults

I believe these checkers will help new users of SolrPlugin, and also fix any configs where {SupportedLanguages} got borked into becoming a string like ... = 'HASH(0x....)';

-- PaulHarvey - 09 Jan 2012

But it needs the Config.spec to have an empty {SolrHome}, otherwise the SolrHome checker won't bother trying to check

-- PaulHarvey - 09 Jan 2012

Added your checkers with some slight modifications to make them work properly.
