Select1 value=position()
Locked
 
|
In a select I want to get have the value of the elements being their
position in the list <xf:select1 bind="selectedGoal" appearance="compact" style="height:10em" id="goalSelect1" incremental="true"> <xf:itemset bind="goals"> <xf:label> <xf:output ref="stml:SequenceIndicator"/> <xf:output ref="stml:Name"/> </xf:label> <xf:value ref="position()"/> </xf:itemset> </xf:select1> However this produces an error about converting an integer to a nodeset This is the instance, the selectGoal is bound to the goal element <xf:instance xmlns="" id="selectedInstance"> <selected> <goal>1</goal> <goalElement></goalElement> <objective>1</objective> <strategy>1</strategy> <url></url> <language>en</language> </selected> </xf:instance> It has just occurred to me that I could save the element and calculate the id <xf:select1 bind="selectedGoalElement" appearance="compact" style="height:10em" id="goalSelect1" incremental="true"> <xf:itemset bind="goals"> <xf:label> <xf:output ref="stml:SequenceIndicator"/> <xf:output ref="stml:Name"/> </xf:label> <xf:value ref="."/> <xf:action ev:event="xforms-value-changed"> <xf:setvalue bind="selectedGoal" value="xxf:bind('selectedGoalElement')/position()/"/> </xf:action> </xf:itemset> </xf:select1> This doesnt give me an error but doesnt work, I guess because the position() isnt with respect to the parent collection but the instance and so gives me the result of 1 always. Any ideas? Thanks in advance Andy Bailey -- You receive this message as a subscriber of the [hidden email] mailing list.

The @ref attribute must always return nodes. position() returns a
number, not a node, hence the error.

Ok great, thanks.
<xf:value value="position()"/> worked, any chance of suggesting this for the next xforms spec. I had to add a cast to number, which Im not sure why. ( is this a bug?) <xf:group ref="instance('stratmlInstance')/stml:Goal[number(xxf:bind('selectedGoal'))]"> Andy Bailey http://www.hazlorealidad.com -- You receive this message as a subscriber of the [hidden email] mailing list.

But feel free to do so as well by sending an email to: [hidden email] > I had to add a cast to number, which Im not sure why.

So in this case you need the cast to tell XPath that you want a numeric predicate as opposed to a boolean one. In the future, it would be desirable to honor node types, as XSLT 2.0 does in schema-aware mode. -Erik -- Orbeon Forms - Web Forms for the Enterprise Done the Right Way http://www.orbeon.com/ -- You receive this message as a subscriber of the [hidden email] mailing list.
