Invalid card objects

If an entire card object is invalid, a runtime message appears in the Command Server window, indicating that the data is invalid. For example, if an input source is a file and the file is invalid, when the map is run, the message "One or more inputs was invalid" may appear.

If you trace the card containing the invalid object, a message in the trace file indicates that the card data object was invalid. If the data object of input card 1 is File and is invalid, the trace file would indicate this with the message "Input 1 exists, but it is invalid".

Prior to the message that the entire card object is invalid, there is an explanation of why it is invalid. For example, it might be that a required component of the card object is in error. The message about the invalid component will contain a negative word such as not, failed, wrong, or invalid.
