Lukasz Lenart updated WW-5784:
------------------------------
Fix Version/s: 7.5.0
> Allow prefix matching of field names on the fielderror tag
> ----------------------------------------------------------
>
> Key: WW-5784
> URL: https://issues.apache.org/jira/browse/WW-5784
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - Tags
> Reporter: Lukasz Lenart
> Priority: Major
> Fix For: 7.5.0
>
>
> Follow-up to WW-3624, which adds a {{regex}} attribute to {{<s:fielderror>}}.
> The most common use of that attribute is showing every error under one path,
> e.g. all errors for a single row inside an iterator. With regex this requires
> escaping by hand:
> {code:xml}<s:fielderror regex="true">
> <s:param>^ledger\.records\[<s:property
> value="#row.index"/>\]\..*</s:param>
> </s:fielderror>
> {code}
> A forgotten escape ({{.}} or {{[}}) silently matches more keys than intended.
> Proposal: add a {{fieldNamePrefix}} attribute that selects every field error
> whose key starts with the given value, with no escaping and no pattern
> compilation:
> {code:xml}<s:fielderror fieldNamePrefix="ledger.records[%{#row.index}]."/>
> {code}
> Scope:
> * {{FieldError}} component and {{FieldErrorTag}}
> * {{simple}} and {{html5}} {{fielderror.ftl}} templates
> * javatemplates {{FieldErrorHandler}}
> The attribute is additive and opt-in; existing exact-name matching and the
> {{regex}} attribute from WW-3624 stay unchanged. How it combines with
> {{fieldName}}, nested params and {{regex}} on the same tag is to be decided
> in the design.
