TicketCreate() assumes falsely that a ticket number looks like a number (an int)

[vincentborghi]

My OTRS instance has a specific ticket number generator, so ticket numbers are not made of digits only (an example of ticket number in my system is "210315-VT1203" ). Apparently (and if I understand), non-numeric ticket numbers cause TicketCreate() to fail when it generates its return infos.

For example I have a ticket number like "210315-VT1203" and I obtained this error (although the ticket is created as expected):
Traceback (most recent call last):
File "./testpyotrs.py", line 45, in

File "./testpyotrs.py", line 37, in createtest
client.tc.TicketCreate(t, a,) # [df1, df2], [att1])

infos = {extract_tagname(i): int(i.text) for i in elements}
ValueError: invalid literal for int() with base 10: '210315-VT1203'

Thanks

Same issue is found when calling TicketUpdate().
...and posibly other places where int(i.text) is applied to the ticket number...

Agreed that the assumption of a ticket number that strictly consists of numbers should be removed. Will think about how to implement this (pull request is also welcome...)

As a workaround, I have modified my python-otrs/otrs/ticket/operations.py as follows (just a quick hack that probably could be even simpler, shown below as a diff). The statement that hurts is:
infos = {extract_tagname(i): int(i.text) for i in elements}

It appears in the "class TicketCreate" and in the "class TicketUpdate" definitions, so I applied the change the change to both places.
