Hi,

Just discovered it today with a colleague.

We used the PP cartridge to index a chemistry data, and then used the protocol to look at the index.

But when trying to get the top 100 compounds it did not work, running, but with no ending.

By digging, we found the problem, there was some records with empty chemistry data.

And the component  Molecule From Text was just hanging when a record has no data.

Example to create it:

Create an empty property, test:=''

Then plug the Molecule From Text, with test as value, and run

And the protocol runs doing nothing and does not stop (no error, nothing). I assume it is trying to find the format, but can't find it, and tries again...

It could be good to have the component sending empty value to the fail port.

The component is inside examples so it is not easy to go everywhere and add a filter to be sure the value is not empty.

Edit: I'm using PP 7.5

Cheers,

Jérémy
