Hi Nicola,
Thank you. I tried the validator as you illustrated, and it worked perfectly.

Greetings,
I am adding a new tool to our in-house Galaxy, which has a few string inputs. I have made each one a text param in the XML, but want to ensure that the user does not leave any empty when he executes the tool.
How can I do this? I tried setting the optional field of each text param to false, but that doesn't work since, technically, an empty string still counts as a string.
Is there a minimum length setting I can enforce?
Hi Ravi, you should use a validator, as in the following example:
<param name="rgid" type="text" label="Read group identifier (ID)"> <validator type="empty_field" /> </param>
Best, Nicola
