@Steinmautz89 Thanks for reporting this! #50 should fix this issue.

Can't reproduce:

>>> from basyx.aas import model
>>> model.Property("abc", model.datatypes.Int, 0).value
0
>>> model.Property("abc", model.datatypes.Int, "0").value
Traceback (most recent call last):

    self._value: Optional[base.ValueDataType] = (datatypes.trivial_cast(value, value_type)
  File "/home/jkhsjdhjs/git/basyx-python-sdk/basyx/aas/model/datatypes.py", line 424, in trivial_cast
    raise TypeError("{} cannot be trivially casted into {}".format(repr(value), type_.__name__))
TypeError: '0' cannot be trivially casted into Int

Can you give a description on how to reproduce this issue?

[Steinmautz89]

Actually it occurs when AASXWriter is used.

[s-heppner]

This could be a limitation of the serialization. Could you verify if the aas file inside the .aasx zip package is a JSON or an XML file?

[Steinmautz89]

It is an XML file.

@jkhsjdhjs could you take a look at how the XML adapter serializes and deserializes 0?
