Limiting the number of characters users can enter into a field

Is there a way to limit the number of characters a user can enter into a field? Our project segment is 7 characters, but the form allows many more than this. The validation catches it on a save, but it would be a better user experience if I could catch it on the front end. Would this be possible in LPL? Any advice would be greatly appreciated!

Thanks,

How does validation catch it on a save?

two ideas:

try a constraint / condition that is (ProjSegmentField size <= 7) or use a transient field of size 7 for form entry and when value changed it into the real project segment field

cleverly

From my reading of the LPL Guide, the closest I think you could get would be to customize the form and add a "show up to 7 characters" line (see page 79) indented beneath the Project field.

But from my quick testing (albeit with a user field, not a delivered field, though I don't see why that would make any difference) it doesn't prevent entry of additional characters—it just sizes the input field, and depending on the label width, might end up even larger than what you asked for anyway. It definitely does not limit entry to only the specified # of characters, which is what it sounds like you are after.

Moving the value from the transient field with a size of 7 to the project field works perfectly. Without this modification when the user enters 8 digits for the project segment, the validation gives an error message on the save that the project does not exist. I appreciate the help!
