Hi,

The following error occurs when the SET_REF command assigns a component reference to a variable that has been defined with a dynamic reference in the DEFINE_COM statement without network connection.
Our customer would not like to show the following error to end users.
Is there any way to handle VL Web runtime script error?

LANSA Runtime Error:
Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://192.168.1.3:3080/x42pgmlib/lansa ... r-jpn.json'.
(Browsers other than Chrome shows NetworkError.)

Thank you in advance.
Best Regards,

There is a parameter on SET_REF for Com_Error.

If you used SET_REF ... COM_ERROR(*IGNORE)
or
SET_REF ... COM_ERROR(*SET_NULL)

would that help solve the problem?

Then you could test whether the component was null before using it.

Thank you very much for your reply.
I tried, but COM_ERROR(*IGNORE) and COM_ERROR(*SET_NULL) couldn't stop that script error.
We will consider to check network connection before assigning a component reference.

This sounds like a potential defect.

COM_ERROR(*SET_NULL) should trap everything.

Could you please report this, which some sample code, via your local LANSA support team?

I will report this to LANSA Support.
Thank you.
