Indexed properties not set correctly in form tags [SPR-6921]

[spring-projects-issues]

Daniel IfCore opened SPR-6921 and commented

Since 3.0.1 the input form tag generates a different html code for indexed properties:

Example:

<form:input path="searchValues[author]" />

searchValues is a Map<String, String> object in the model.

In 3.0.0 the resulting html was:
<input id="searchValuesauthor" name="searchValues[author]" type="text" value=""/>

3.0.1 now generates:
<input id="searchValuesauthor" name="searchValuesauthor" type="text" value=""/>

This results in unset properties in the model property searchValues.
When I modify the parameter name in the request manually to the old form, the values are set correctly.

Affects: 3.0.1

This is an unfortunate regression in 3.0.1 which has been fixed in recent 3.0.2 snapshots already. Feel free to give 3.0.2 early try; it's scheduled for release next week.

just ran into that problem, with 3.0.2.BUILD-SNAPSHOT it works again - thanks!
