form tags path attribute leaving square brackets out of id attribute of html tag [SPR-4698]

[spring-projects-issues]

Matthew Tatum opened SPR-4698 and commented

I have a problem that since moving from Spring 2.0 to Spring 2.5 form tags that render collections are working slightly differently.
<form:input path="myCollection[${index}].myValue" />
previously rendered as:
<select id="myCollection[0].myValue" name="myCollection[0].myValue" />
and is now rendering:
<select id="myCollection0.myValue" name="myCollection[0].myValue" />

Notice the lack of square brackets in the id attribute. This may not seem like much but we have a lot of javascript that relies on it rendering the first way!

I'm afraid you'll have to adapt the affected JavaScript, since that change was deliberate... We had to change the id generation strategy to always produce valid HTML ids - which unfortunately means excluding such brackets. Sorry for the inconvenience!

See #7069 for the original issue that triggered this change.

Thanks Juergen,

We can work around that!
