Hoss Man commented on SOLR-3633:
--------------------------------
bq. I'll attach an small and simple patch which also shows an warning screen
but with a specific message, for no cores being loaded
steffkes: I haven't had a chance to look at your patch yet, but it sounds like
what i was going for in the SOLR-3677 subtask (i'm assuming your patch is
probably better then mine since you actually understand the UI internals and
i'm just beating on it with a stick until it kind of looks like what i was
hoping for).
Even if there's no good way to make the bulk of the UI work w/o a Core, i think
we should...
* commit something in SOLR-3677 ASAP to deal with the better "error" message
so we're sure it's addressed in 4.0.0
* wrap up SOLR-3591 in some way that core init errors are visibile in the UI
even if there are no cores
* leave SOLR-3633 open to think about ways to try and make the UI work better
with no cores -- at a minimum it would be nice to still offer an "Add Core"
button, even if it ment having a special "you have no cores, so the ui looks
totally diff and all you have is an Add core form" screen.

> Spun off from SOLR-3591...
> * having no SolrCores is a valid situation
> * independent of what may happen in SOLR-3591, the web UI should cleanly deal
> with there being no SolrCores, and just hide/grey out any tabs that can't be
> supported w/o at least one core
> * even if there are no SolrCores the core admin features (ie: creating a new
> core) should be accessible in the UI
