Extension actions

The <xxf:setvisited> action

The <xxf:setvisited> action allows updating the "visited" flag of a control. It has the following attributes:

• control: id of the initial control to update

• visited: if true, mark the control(s) as visited, otherwise as not visited

• recurse: if true, update the given control as well as descendant controls, otherwise update just the specified control

All attributes are AVTs.

Example:

<xxf:setvisited
    control="{$control-id}"
    visited="true"
    recurse="true"/>

See also the xxf:visited() function.

Extension attributes

xxf:deferred-updates

The xxf:deferred-updates attribute is supported on the following actions:

• <xf:setfocus>

• <xf:setindex>

• <xf:toggle>

By default, as per XForms 1.1, these actions first invoke deferred update behavior.

Setting this attribute to false disables invoking deferred update behavior. This can lead to performance improvements when a large number of such actions run in a sequence.

This attribute is an AVT which allows for dynamic evaluation of the attribute.

Examples:

<xf:setindex
    repeat="my-repeat"
    index="2"
    xxf:deferred-updates="false"/>

<xf:setindex
    repeat="my-repeat"
    index="2"
    xxf:deferred-updates="{count(item) > 0}"/>

Option to not toggle ancestors <xf:toggle> controls

[SINCE Orbeon Forms 2021.1]

With Orbeon Forms, the <xf:toggle> action also causes ancestor <xf:switch> controls, if present, to toggle so that every ancestor <xf:case> is visible.

Orbeon Forms adds an extension attribute, xxf:toggle-ancestors="false", which allows toggling only the given <xf:switch>, even if it is contained within ancestor <xf:switch>/<xf:case> controls that are not visible, without toggling those.

For example, with:

<xf:switch id="my-outer-switch">
    <xf:case id="my-outer-case-1"/>
    <xf:case id="my-outer-case-2">
        <xf:switch id="my-inner-switch">
            <xf:case id="my-inner-case-1"/>
            <xf:case id="my-inner-case-2"/>
        </xf:switch>
    </xf:case>
</xf:switch>

Assuming, initially:

• my-outer-case-1 is selected

• my-outer-case-2 is deselected

• my-inner-case-1 is selected

• my-inner-case-2 is deselected

The following action:

<xf:toggle 
    case="my-inner-case-2"
    xxf:toggle-ancestors="false"/>

Produces the following result:

• my-outer-case-1 remains selected

• my-outer-case-2 remains deselected

• my-inner-case-1 is newly deselected

• my-inner-case-2 is newly selected

While the default behavior, with action:

<xf:toggle 
    case="my-inner-case-2"/>

Produces the following result:

• my-outer-case-1 is newly deselected

• my-outer-case-2 is newly selected

• my-inner-case-1 is newly deselected

• my-inner-case-2 is newly selected
