Error writing output with iview for xml form builder

Question

Hi,
I created a Xml Form Builder's project in which I developed an "Edit" and "ListEdit" sheet.
I also created an iview for theese in which the code link is:"com.sap.km.cm.xmlform",and the field for Style Sheet for List and for single item are set up correctly,but when I tried the preview the following error message happened:
com.inqmy.lib.xsl.xslt.XSLOutputException: Error writing output. -> org.w3c.dom.DOMException: Root Element is already present, cannot be appended as a child.
could someone help me?
thank's a lot!

Hi,
Now I'm confused,what do you mean with create new data? Are users editing existing documents
(as if they go to a document example.xml > edit) or they are creating new documents (as if they go
on folder > new > forms)?
The problem is, in both cases a user would need read/write permissions.
The normal flow content (data) is created in KM is as follows:
1. user is assigned to a role
2. role contains KM Navigation iView
3. KM Navigation iView executes com.sap.km.cm.navigation component
4. user chooses New > Form UI command (edit_xml_forms)
5. edit_xml_forms UI command executes its code (com.sapportals.wcm.rendering.uicommand.cm.UIXMLFormsCreateCommand) and open xml edit for the user
6. user fill the form and click Save, form is created into folder
For what I understood so far, your requirement basically asks you to go directly to step 5, it is
possible to pass a URL that goes directly to step 5, the UI command button, but if you do that
you won't have a context, so chances that it will work are slim, since a context is required to
fill the parameters asked by the app (like folder, user, permissions, etc). Even though, in some cases you can
still pass the parameters via post in the URL but you must know which service/parameters the
app asks for it, also a URL is static...
That was the create scenario, I think it's more cons than pros, users would still be
able to bypass the URL iView created for that, I'd suggest evaluating again if it's really
a problem having users access cm to manage data
kind regards,
