handle Technology selected without any Projects

[bbest]

From MarineEnergy.app_Review_GCS_120921.docx - Google Docs:

Projects page – an error occurs if one selects a technology that is not available (e.g., Current or Offshore Wind). Only Riverine, Tidal, and Wave work. We need to have a solution for this.

SOLUTION

Present something like:

Sorry, the Technology {tech-selected} does not match any available Projects. Instead, please select one of the following available technologies: {tech-available-list}.

Preferably:

• color code (i.e. blue banner) each Technology

[bbest]

Step 1. Empty Map & Timeline

Step 2. Add message to app

Here:

using:

• conditionalPanel() in ui.R
• reactiveValues() in server.R for some variable like msg_projects starting with value of NULL and then if a condition arises replacing or appending to show.
• ixn_to_colorhtml() in scripts/shiny_report.R

1. Select OTEC

2. Get message without Map or Timeline

3. Add Riverine

4. Get message still for OTEC, but Map and Timeline show for Riverine
