class %ZEN.Component.repeatingGroup
extends group, querySource
A specialized group that repeats its contents based on run-time data.
A repeating group executes a query and, for each row of the results,
creates HTML for all of the members of the group. For example:
<repeatingGroup sql="SELECT Name FROM Sample.Person">
<button caption="Press" onclick="alert('#(%query.Name)#');"/>
</repeatingGroup>
Each row within the repeating group is referred to as a
tuple.
For each tuple, the repeating group renders HTML for each of its child components.
Note that only one object is created for each child of the repeating group but
there are multiple HTML renderings (one per tuple) for each child. The rendered
HTML incorporates the current tuple number into the id values used to identify HTML
elements to keep track of them.
Applications should keep use of repeatingGroups reasonably simple.
Repeating groups within repeating groups are not supported.
