Handling exceptions in beans #480

Open squaregoldfish opened 7 years ago

squaregoldfish commented 7 years ago

Most bean methods simply throw their exceptions. These are either completely unhandled, or will fail silently because the ajax doesn't handle error conditions.

Use the internalError method for main actions. Work out what to do with ajax calls.

There is a global exception handler in JSF, and apparently OmniFaces has a good exception handler for AJAX calls, so it's likely that PrimeFaces does too. (See page 224 of the Mastering JSF book)

882/#883 has added a global exception handler that simply dumps all exceptions to the console. It's a start but we need something more sophisticated and that actually tells the user what's happening.

squaregoldfish commented 4 years ago

An example is being made in the new QC/Plot pages. Perhaps it should be extended to all beans that do ajaxy things...
