What happened?

There seems to be an issue unique to the Table Input step where the Output Fields functionality hangs forever when there is not a valid DB connection. This comes up when converting existing KTRs from Pentaho as well as net new pipelines.

Set up a dummy pipeline with dummy table input configuration. The table input can either have a blank connection or one populated that is not configured/does not connect to anything.

When clicking Output Fields on the Table Input step, it will hang forever. Clicking cancel doesn't work, and you have to terminate HOP GUI and restart to do anything.

This seems to be unique to Table Input, as the text file inputs, salesforce input, etc will error out properly. This is a bit painful and feels like something that should be timing out rather than hanging/freezing.

I'm a Pentaho veteran but new to Apache HOP - so be kind please ;)
