autoincrement xforms:setvalue inside xforms:repeat

I'm trying to autoincrement an 'id' attribute in an XML instance (just like in MySQL) .
I found some topics here on autoincrementing element values , but those didn't work for me either.

So , my instance looks like this :

<nabble_embed><xforms:instance id="faculties-instance"> <faculties xmlns=""> <faculty id=""> <name /> </faculty> </faculties> </xforms:instance></nabble_embed>

(I'm not sure if the id attribute is represented correctly in the instance , I didn't find any documentation on this)

And the code inside xforms:repeat looks like this :

<nabble_embed><xforms:repeat nodeset="faculty" id="faculty-repeat"> <tr> <td> <xforms:trigger appearance="minimal"> <xforms:delete ev:event="DOMActivate" context="instance('faculties-instance')" nodeset="faculty" at="index('faculty-repeat')"/> <xforms:label><img src="/apps/xforms-bookcast/images/remove.gif"/></xforms:label> </xforms:trigger> </td> <td class="form-td"> <xforms:input ref="name"> <xforms:label class="faculties-label">Name</xforms:label> <xforms:alert>The faculty name is required</xforms:alert> </xforms:input> <xforms:action ev:event="DOMActivate"> <xforms:setvalue ref="instance('faculties-instance')/faculty[index('faculty-repeat')]/@id" value="index('faculty-repeat)" /> </xforms:action> </td> </tr> </xforms:repeat></nabble_embed>

Instead of instance('faculties-instance')/faculty[index('faculty-repeat')]/@id , I also tried using context()/@id , current()/@id - none of them worked.

Thanks in advance !

Vlad,

There are more than one ways to determine what that id should be. Here
I assume "max(id) + 1".

<xforms:setvalue ref="@id"
value="max(instance('faculties-instance')/faculty/@id/xs:integer(.)) +
1"/>

One question is: when do you want to call this? I would assume upon
inserting a new row.

BTW you can write your delete this way:

<xforms:delete ev:event="DOMActivate" ref="."/>

Re: autoincrement xforms:setvalue inside xforms:repeat

That xforms:repeat piece of code is used for dislaying and also for adding/editing .
So I guess I'll use some conditional structure , like :
<nabble_embed><xforms:action if="not(@id)"> <xforms:setvalue ref="@id" value="max(instance('faculties-instance')/faculty/@id/xs:integer(.)) + 1"/> </xforms:action></nabble_embed>

For the 'else' branch (when @id value is set) I think that the value is kept without explicitly specifying it . Am I right ? (I cannot test it right now , I'll be back later)

Re: autoincrement xforms:setvalue inside xforms:repeat

It still doesn't work , I think that the <xforms:setvalue> is not executed.

The <faculty> elements are saved in eXist with id="0" , the default value that I defined in the instance :

<xforms:instance id="faculties-instance">
<faculties xmlns="">
<faculty id="0">
<name />
</faculty>
</faculties>
</xforms:instance>

I declared the attribute in XSD :
<xs:attribute name="id" type="xs:integer"/>

This is the binding :

<xforms:bind nodeset="instance('faculties-instance')/faculty">
<xforms:bind nodeset="@id" required="true()"/>
<xforms:bind nodeset="name" required="true()"/>
</xforms:bind>

And this is faculty-template , which I specify as an "origin" (attribute) when the new element is generated :

<xforms:instance id="faculty-template">
<faculty id="0" xmlns="">
<name />
</faculty>
</xforms:instance>

Maybe I didn't place the <xforms:setvalue> in the right place ?

Thanks.

Re: autoincrement xforms:setvalue inside xforms:repeat

This post was updated on .

I found the problem , "Note: <xf:repeat> does not work inside <xf:action>" asa specified here : http://en.wikibooks.org/wiki/XForms/Select_All
So my solution is :

<xforms:action if="number(instance('faculties-instance')/faculty[1]/@id) < 1">
<xforms:setvalue ref="instance('faculties-instance')/faculty[1]/@id" value="max(instance('faculties-instance')/faculty/@id/xs:integer(.)) + 1" />
</xforms:action>

(put this code outside of <xforms:repeat>)

(faculty[1] , because the newly-added elements are put first)

Good to hear you found the issue.
