Error while click preview button in custom print form


I create custom print form for Opportunities and bind EC to Attachment tab . When I click to Preview button,

I get dump like this;

"Unable to get "_a" property of undefined or empty reference."

But I do not use "_a" anywhere. How can I fix this?

    For the PreviewOutports bound to EC, there could be cases where an inconsistency raised in the targetcomponentID if the full path is not stored.

    This needs to be corrected/fixed and so it is advised to report an incindet to SAP Support for more details
