add exception for text in scan_id

[rodolakis]

• close #129

The behavior that would make the most sense to me if some text is entered would be to return an empty catalog (anything else triggers a lot of error since a catalog is expected to be returned). That would clear the tableview, clearly showing that the user did something wrong. I found this:

from tiled.catalogs import Catalog
empty_catalog = Catalog.from_dict({})

but I think our version of tiled is too old:

In [1]: import tiled

In [2]: print(tiled.__version__)
0.1.0a89

In [3]: import tiled.catalogs
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[3], line 1
----> 1 import tiled.catalogs

ModuleNotFoundError: No module named 'tiled.catalogs'

I agree that once tiled is updated (#53), this code should be adjusted per the TODO comment.

Add that issue number to the comment on line 81.

This fails silently. It could report the exception to the statusbar. That would coach the user about why this query failed.

The problem I encountered several times yesterday is that the status bar tends to be overwritten but other messages. I don't have specific examples though, I will try to document this.

I added the reference to both this PR and issue #53. I also added an update to the status bar: https://github.com/BCDA-APS/gemviz/blob/47c27e232e9dffc4de2056ebee33d71ada052064/gemviz/bluesky_runs_catalog_search.py#L80

However like I said earlier, the status bar is overwritten by the displayTable call. We need to somehow pass that information to the slot?

A history (or logging) window might be an addition. In a new issue.
