InfoPath Dev

Hi

I'm having a problem where InfoPath kills my working schema mySchema.xsd. I have the following:

<xsd:element name="list">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="my:list-item" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute name="is-condition-list" type="xsd:string"/>
<xsd:attribute name="type" type="xsd:string"/>
</xsd:complexType>
</xsd:element>

I can easily populate these "lists" attributes easily in code like this:

Dim newListNode As IXMLDOMNode = sectionsNode.ownerDocument.createNode(DOMNodeType.NODE_ELEMENT, "my:list", myNameSpace)
Dim listType As IXMLDOMAttribute = sectionsNode.ownerDocument.createAttribute("my:type")
Dim isConditionList As IXMLDOMAttribute = sectionsNode.ownerDocument.createAttribute("my:is-condition-list")
listType.text = theDeterm.sections(i).list.type
isConditionList.text = theDeterm.sections(i).list.isconditionlist
newListNode.attributes.setNamedItem(listType)
newListNode.attributes.setNamedItem(isConditionList)

Problem is, whenever I save my form Infopath goes and changes my schema to

<xsd:element name="list">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="my:list-item" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute ref="my:is-condition-list"/>
<xsd:attribute ref="my:type"/>
</xsd:complexType>
</xsd:element>

Note the attribute ref's.

I'm not too fussed about that except it breaks my code. Everytime I try to create the attribute and attach it to the node in Managed code (as per above), InfoPath says the attribute doesnt belong.

This is an example (on another schema element).. and Yep I've checked that it exists and is fine.. it works fine before infopath molests it and changes it to ref=

System.Runtime.InteropServices.COMException
The attribute 'heading' on the element 'http://schemas.microsoft.com/office/infopath/2003/myXSD/2005-10-31T06-47-55}section' is not defined in the DTD/Schema.

Hi Adam,

you could try 2 things:
1. Work with your attributes as if they were nodes, not attributes (if you built your schema using InfoPath).
2. Keep you code but create your schema with XMLSpy.

Tell me if it helps.

I'll try this one. Thanks.

This is what I've been doing this far but it just breaks everytime I save my Infopath form as Infopath goes and molests the schema and overwrites it. :(

Adam,

Did you try with a schema built in IP? IP won't overwrite that for sure.
If you are using XMLSpy an IP is overwriting things, you have a prefix/Namespace issue.
