Powerbuilder Classic 12.1 - PBDOM issue

Hello all,

I'm generating XML files through the PBDOM120.PBD library.

I implemented the code to generate the XML file and it's working fine, but sometimes (it happens once in 10 executions, for example) I get the error "bad runtime function reference" when I call the function "NewDocument(string strRootElementName)" (class: PBDOM_DOCUMENT).

After each execution I destroy the all the objects involved. I don't know what I'm doing wrong. Could it be a powerbuilder's bug? I'm using the version 12.1 build 6875.

Somebody could help me with this matter?

Thanks in advance.

Vinicius Petrolli.
