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}"/>
