Let me try to better describe what the problem is...
Let's say i create an Autocompleter, using
<input jwcid="@Autocompleter" id="europe:countries" ... />
Here's the generated html:
<select name="europe:countries" autocomplete="off" disabled="disabled"
id="europe:countries"></select>
and it's valid.
But, in the case of the Autocompleter, that id (europe:countries) is also used
to generate javascript
identifiers, so here's some js that gets generated:
var europe:countriesprop={"dataUrl":"blah", ... }
which is clearly invalid.
So, i see 3 solutions:
-) put out a big warning to users and component authors saying:
please DO NOT use - or : or . in your ids cause even though valid, we might
use them as javascript variable names.
-) escape those characters either always or before using them in .script files
-) use a different way to create those javascript identifiers, one that doesn't
depend on ids. For instance, instead of
var ${id}prop=something
do
<let key="betterId" unique="true">prop</let>
and then
var ${betterId}=something
A hybrid solution between 2 and 3 would be to allow an extra attribute for let,
and use it as:
<let key="betterId" unique="true" javascript="true">${id}</let>
Anyway, please share your feelings about this.
P.S. This issue initially occurred while creating a new FormSupportImpl... in
there i generate ids for
form elements that go like this: form_id:element_id
