Bertrand Guay-Paquet commented on WICKET-5242:
----------------------------------------------
Well I'm pretty sure I had a usecase, but I can't reproduce any problem either
across 4 browsers... I also don't understand why the referenced email thread
was started if this wasn't a problem. I'll close the issue for now.
> Disable escaping of html tag attributes
> ---------------------------------------
>
> Key: WICKET-5242
> URL: https://issues.apache.org/jira/browse/WICKET-5242
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 6.7.0
> Reporter: Bertrand Guay-Paquet
> Labels: escaping, html, tags
>
> Currently, all component tag attributes are escaped.With html5 data-
> attributes, much more values can be considered valid depending on the tag
> attribute and some should not be escaped.
> For example, bootstrap tooltips use the "data-title" attribute to set the
> content of a tooltip. Using Wicket's tag attributes, it's not possible to set
> the value "<b>hello world</b>" as the data-title since it is escaped.
> ComponentTag#writeOutput() is the method which calls
> Strings.escapeMarkup(value); and escapes tag values. This is called by
> Component#renderComponentTag().
> There should be a way to disable component tag escaping either per-tag or
> per-component.
