conditional action on submission response

Hi,

I'm trying to conditionally respond to a submission response according
to the value of one of the response instance's element values.  This is
what I have now, but the second action is the only one that ever fires.
(I'm 99% certain that I am in fact sometimes returning a non-empty
elementValue - I'm going to trace that to be sure later today..)

      <xforms:action ev:event="xforms-submit-done"
                     observer="mysubmission"
                     if="string-length(instance('submission-response')//elementValue) > 0">
        <xforms:message level="modal" ev:event="DOMActivate">Non-Empty String</xforms:message>
        <xforms:toggle case="case-non-empty" />
      </xforms:action>

      <xforms:action ev:event="xforms-submit-done"
                     observer="mysubmission"
                     if="string-length(instance('submission-response')//elementValue) = 0">
        <xforms:message level="modal" ev:event="DOMActivate">Empty String</xforms:message>
        <xforms:toggle case="case-empty" ev:event="DOMActivate" />
      </xforms:action>

So I guess I'm wondering why this doesn't work.  I'm also curious how
other folks would do this.  Is there a common pattern for doing an
'else' action, or is the pattern to simply create two mutually exclusive
'if' actions?

TIA

-Ron-

Hi Ron,

Try putting both of your if statements inside the same action inside the submission.  So:

<submission>
        <xforms:action ev:event="xforms-submit-done">
                <xforms:action if="string-length(instance('submission-response')//elementValue) > 0">
                        <xforms:message level="modal" ev:event="DOMActivate">Non-Empty String</xforms:message>
        <xforms:toggle case="case-non-empty" />
                </xforms:action>
                <xforms:action if="string-length(instance('submission-response')//elementValue) = 0">
                        <xforms:message level="modal" ev:event="DOMActivate">Empty String</xforms:message>
                        <xforms:toggle case="case-empty" ev:event="DOMActivate" />
                </xforms:action>
        </xforms:action>
</submission>

And when the xforms-submit-done action fires, the if statements will be evaluated and only the contents of the correct statement should fire.

Hope that helps,
Stephanie

Thanks Stephanie,

I hate to fess up to my error, but just in case anyone ever refers to this later..

Both forms work OK.  My problem was that I forgot to add the namespace
prefix for the element I was referring to.

instance('submission-response')//elementValue
instance('submission-response')//ds:elementValue

Not true.  Yours is better.  My way doesn't discriminate between
different submissions.  I thought the observer attribute directs an
action to pertain to a specific submission, but I apparently don't
properly understand the observer attribute yet.
