Antonio Petrelli updated TILES-83:
----------------------------------
Fix Version/s: (was: 2.0.x)
2.1.x
> Add to <putList> the ability to add elements to an overridden list attribute
> ----------------------------------------------------------------------------
>
> Key: TILES-83
> URL: https://issues.apache.org/struts/browse/TILES-83
> Project: Tiles
> Issue Type: New Feature
> Components: tiles-core
> Affects Versions: 2.0.0
> Environment: All
> Reporter: Antonio Petrelli
> Priority: Minor
> Fix For: 2.1.x
>
>
> Currently the <putList> element in Tiles definitions configuration files and
> <tiles:putList> tag, in the case of a definition extending another
> definition, or inserting a definition with an overridden attribute, replaces
> the previous attribute list with new one.
> For example:
> <definition name="baseDefinition" template="/template.jsp">
> <putList name="listAttribute">
> <add value="First string" type="string" />
> </putList>
> </definition>
> <definition name="extendedDefinition" extends="baseDefinition">
> <putList name="listAttribute">
> <add value="First string" type="string" />
> <add value="Secondo string" type="string" />
> </putList>
> </definition>
> As you can see, the "First string" value is duplicated.
> A new attribute, for example "clear" (that defaults to "true" for
> compatibility reasons) can be used to specify if the list should be cleared
> or not.
