Duplicate Elements in Doctypes

, ,

X-Application Version : 3.1.1
Tamino Version : 3.1.1.1
Platform : NT
WebContainer : Tomcat 4.0
JDK Version : 1.3.1_01

Question:
I have a Tamino collection containing two doctypes. Element “custname” appears in both doctypes in the schema. If I try to generate an X-Application for either doctype, I get the following exception. Can this by bypassed in any way?

Exception:

code:

Hello Bill,

currently X-Application does not support schema documents which contain two element declarations with the same name. A possible workaround for this problem could be:

  • A to use a reference if the two schema use the same element ?custname? :
    for example:



    …

    …



    …

    …

    …


  • B to split the schema document if the two schemas contain an element ?custname?, but the element is different .
    For example for your ?customer? schema it is a complex type and for ?resource? schema it is a simple string:



    …






    …



    …

    …


    When the schemas are stored within two different documents, X-Application will also create two different objects for the schema information and the conflict for ?custname? does not longer appear.

I hope (A) or (B) will be an acceptable workaround for your problem.

Good bye,
Christian.
