Ryan Holmes commented on WICKET-995:
------------------------------------
On second thought, the issue I described above could occur right now, since you
can use '_' in a component id (plus I hadn't read Igor's latest comment).
Perhaps a substitution character other than '_' should be considered.
I have to bring up one more criticism though. If this is a good idea, shouldn't
Wicket also transform other characters that could be confusing, although legal,
in a CSS context? For example, a space.
> getMarkupId generates ID which contains special characters which should be
> escaped or replaced

> Key: WICKET-995
> URL: https://issues.apache.org/jira/browse/WICKET-995
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.0-beta3
> Reporter: Alexandru Objelean
> Assignee: Igor Vaynberg
> Fix For: 1.3.0-beta4
>
>
> This is about how wicket generates dynamically markupID.
> I have, for instance, the following markup component:
> <input wicket:id="quantity.noOfUnits" />
> The generated markupId for this component looks like the following:
> quantity.noOfUnits1232 .
> I suggest to escape any css valid specifiers from the generated markupId, by
> replacing them with something else (for instance '_' character).
> The problem appear when I am trying to identify the component by it's id
> using some js library (like jQuery) and as a consequence the result of this
> query: $("#quantity.noOfUnits1232") is invalid.
