Using array syntax generates invalid id [SPR-2380]

[spring-projects-issues]

Bjørn Sættem opened SPR-2380 and commented

The tag <form:input path="array[0]" />

generates

<input id="array[0]" name="array[0]" type="text" value=""/>
but "[" and "]" are invalid in an identifier name. Ref. http://www.w3.org/TR/html4/types.html#type-name

Seems quite easy to change generated id to array0, which would be valid.

In AbstractDataBoundFormElementTag
protected String autogenerateId() throws JspException {
return getName().replaceAll("[", "").replaceAll("]","");
}

Of course a workaround is to specifiy the id explicitly...

I've finally addressed this for Spring 2.5, so that no custom ids have to be specified in such a case anymore (in order to get valid HTML ids).

Thanks for raising this issue again, Fried!

The same is happening in spring 2.5 with freemarker.

The same is happening in spring 3.0.6 with freemarker.

<@spring.formInput path="lead.additionalSalesList[1].saleResult.policyId" attributes='class="policyId_1"'/>

generates

<input id="additionalSalesList[1].saleResult.policyId" class="policyId_0" type="text" value="" name="additionalSalesList[1].saleResult.policyId">

This issue covered Spring form tag library generated id on JSP views/forms (see example in issue description), fix works OK, so IMO this issue shouldn't have been reopened, and should be closed now again.

A separate ticket, #13374, covers related issue on FreeMarker views/forms.

Issue was resolved a while ago for JSP tags. A separate ticket tracks the same for Freemarker #13374.

Sivakrishna, are you using Freemarker?

If so, then this is fixed in 3.2 M1 which is not released yet, but you have 3.2 snapshot builds in Spring snapshot repository or you can build latest Spring yourself (see this for instructions).

Otherwise, e.g. if it's issue in JSP views, feel free to provide sample reproduction project. If it's neither in JSP nor Freemarker, but in some other view technology instead, file a new JIRA ticket and attach a sample reproduction project.

See this guide on contributing Spring framework issue reproduction projects: https://github.com/SpringSource/spring-framework-issues#readme

Stevo Slavić commented

Sivakrishna, this is expected behavior, result of a fix. IMO this issue can be closed as fixed in 2.5.
