control the numbers of a repeated component in a node

Dear all,

I’ve used the following code which allows forms users to add single text-line in their form each time they click the “add button” :

<fr:repeat nodeset="responsable" id="responsable-repeat" origin="instance('responsable-template')" columns="1" appearance="xxforms:table">

<fr:body>

<fr:tr>

<fr:td>

<xforms:input id="note-control" ref="." appearance="xxforms:autosize" incremental="true">

<xforms:label ref="$form-resources/responsable/label"/>

</xforms:input>

</fr:td>

</fr:tr>

</fr:body>

</fr:repeat>

It works perfectly however, I would like to have maximum 5 single text-line and one for the minimum.

Does anybody have an idea ??

Regards,

Ilan

Ilan,

From the XForms 1.1 specification:

"Specifying minimum and maximum occurrences for nodes in the instance
data can be achieved by using the count() function within a constraint
property."

So in your model, use a bind to add a constraint using the count() function.

In reply to this post by Ilan Cohen

Ilan,

One way to enable/disable a trigger (the "add button") is to bind it (ref=)

to a node, such as the node that contains the number of lines added.

In turn, the node needs a binding where the relevant attribute is

calculated, e.g.,

relevant="(.< 4) and (. > 1)"

A trigger bound to a reference that is not relevant will be disabled.

Something that is not much discussed ... that besides the instance

you submit, you need one for form control.

HTH,

Hank

RE: Re: control the numbers of a repeated component in a node

Hank,

Thank you for the answer.

I’m using the <fr:repeat nodeset= …> code. So I don’t have triggers . I know that with triggers, and the relevant attribute, I can set bounds for the added components. I already try it and it does work.

However, when I set this code to add component in my form, I had another problem described in the mail named “[ops-users] add components wich contain different value in a form” :

Each time I enter a value in on one of the single line text added by my trigger, the others single line text of the same node automatically take the same value.

So I change my code and choose the fr:repeat .

Regards

Ilan

fr:repeat supports the minOccurs/maxOccurs attributes (e.g. minOccurs="2" maxOccurs="6"). If you don't want to have a constraint on the mix or the max you can just ignore that particular attribute.
