Description

Timeline actually works only with WMTS-Multidim extension. If this extension is not present but a time dimension is anyway present, you have some functionalities not working.

So we should prevent failures and finalize support, or at least avoid errors.

In case of Bug (otherwise remove this paragraph)

Browser Version Affected

any

Steps to reproduce

• Add a layer with time dimension for a server that do not have wmts-extension

Expected Result

• The layer should work or at least not appear inside the timeline (until WMS time in capabilities is not fully supported)

Current Result

• Snap doesn't work
• playback forward-backward buttons do not work
• Autoselection of layer do not work (the layer should be automatically selected as guide/leading layer of the timeline, and if the current time is not set yet, it should go to the last value).

Other useful information (optional):

Timeline was originally made to work with values coming from the capabilities, in configuration or from configuration.
Originally there was also support for continuous interval data, or time values with start/end.

Anyway for now only the WMTS Multidim extension should be supported. You should check what the functionalities at least in the WMS getCapabilities use case and try and error to make MapStore stable even in this use case (if the bugfix are quick and anything works, we may already add support to fixed values, otherwise disable it by removing the time dimension from layer's configuration when the service is not available).

note: the bug reported above has been reported by @allyoucanmap that worked on geonode integration without the wmts-extension. This is a peculiar case that is not supported.
So you may not find the error above testing pure MapStore agains pure GeoServer (without wmts-extension).
In this case, simply check what happens adding layers with "time" dimension from WMS/WMTS catalogs without WMTS-Multidim extension.
