Joseph,
    Quite correct, my bad, it was very early and i didn't fully read the email :-)

Hi Ryan,
    I made the assumption that Larry's trigger was referring to the node to which the attribute need to be inserted. The reason is that before he was using the following code:

<xforms:insert nodeset="." position="after" at="1"
origin="instance('my-attribute')/@attr1"/>

While insertion, the attribute that need to be inserted is obtained from the @origin which points to the template attribute. I expected something like

<xforms:trigger ref="instance('main')/name">
<xforms:label>Insert Attribute</xforms:label>
<xforms:insert nodeset="@*" position="after" at="1" origin="instance('my-attribute')/@attr1" ev:event="DOMActivate"/>
</xforms:trigger>

What I expect here is to get the @attr1  added  as an attribute to  instance('main')/name.  And  it seems to  work  as well.

Thanks

Joseph,
    This will copy all the attributes that exist, but Larry wants to create an attribute from an element

Larry,
    I'm not sure if this is the only way, but I would create a template instance with my attribute in it

<xforms:instance id="template-instance">
    <instance some-attribute=""/>
</xforms:instance>

Then you can insert this attribute, using xforms:insert and set its value using xforms:setvalue

Hope this helps

Hi Larry,
    Hopefully the following modification in your code might work.

<xforms:insert nodeset="@*" position="after" at="1"
origin="instance('my-attribute')/@attr1"/>

    If in case it doesn't, please check whether the sample I am attaching suits your requirement.
    In the attached sample you have a repeat contol and two trigger controls. 1st trigger control is for inserting a node, which once inserted shows up in the list generated by the repeat control.
    The 2nd trigger control inserts an attribute with the value we input to the node selected by the repeat control. In case such an attribute already exists an alert message will be shown.

Thanks

Alex,

I've been using this sort of insert with nodeset pointing to an element.  I'm basically trying to create an attribute on an element if it doesn't already have that attribute.  Should nodeset be pointing to an attribute instead?  But then wouldn't it be impossible to insert an attribute if it doesn't already exist?

Hi Larry,

Yes, there were changes very recently in the specification related to
the <xforms:insert>. In your example, what does nodeset point to? Is
it another attribute or an element?

Hi All,

Inserting an attribute using something like

<xforms:insert nodeset="." position="after" at="1"
origin="instance('my-attribute')/@attr1"/>

used to work in the nightly builds some weeks before the 3.5 release.
Since I upgraded to the 3.5 release, insert actions of this sort stopped
working.
Does anybody know if there was a change to the specs of how
xforms:insert works?  Am I missing something in the insert action?

Larry
