2498 (09C2) (RC2498): MQRC_MIXED_CONTENT_NOT_ALLOWED
Explanation
An attempt was made to set a property with mixed content. For example, if an application set the property "x.y" and then attempted to set the property "x.y.z" it is unclear whether in the property name hierarchy "y" contains a value or another logical grouping. Such a hierarchy would be "mixed content" and this is not supported. Setting a property which would cause mixed content is not allowed. A hierarchy within a property name is created using the "." character (U+002E).
Completion code
MQCC_FAILED
Programmer response
Valid property names are described in Property names. Change the property name hierarchy so that it no longer contains mixed content before re-issuing the call.
