Henrik Brautaset Aronsen commented on WW-3069:
----------------------------------------------
To elaborate further: How will the template / fieldError cope with
MyAction.getForm().getEmail() vs. MyAction.getEmail() if they both are referred
to as <s:fielderror fieldName="email" />?
> Migration from 2.0.x to 2.1.x: fieldError does not use the full parameter
> name as id

> Key: WW-3069
> URL: https://issues.apache.org/struts/browse/WW-3069
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.1.6
> Reporter: Henrik Brautaset Aronsen
>
> After upgrading from Struts 2.0.11 to 2.1.6, fieldErrors weren't displayed
> next to form fields any more. The validation still worked, because I could
> still see the errors by issuing a <s:fielderror/>.
> My form is a value on the action, and is addressed like this:
> <s:textfield label="Your e-mail address" name="form.email" theme="mytheme"
> />
> I noticed that to access a separate value in fieldError in 2.1.6, I had to
> chop off "form.":
> <s:fielderror fieldName="form.email" /> <!-- doesn't show anything -->
> <s:fielderror fieldName="email" /> <!-- shows the error-->
> Now, to be able to show my error using my template, I had to add an ID to my
> textfield:
> <s:textfield label="Your e-mail address" id="email" name="form.email"
> theme="mytheme" />
> Then I had to change the default hasErrorField assignment in the
> controlheader.tpl template:
> <#assign hasFieldErrors = parameters.name?? && fieldErrors?? &&
> fieldErrors[parameters.name]??/> <!-- does not work -->
> <#assign hasFieldErrors = parameters.id?? && fieldErrors?? &&
> fieldErrors[parameters.id]??/> <!-- works as intended -->
> And change way I fetched errors in my controlfooter.tpl:
> <#list fieldErrors[parameters.name] as error> <!-- does not work -->
> <#list fieldErrors[parameters.id] as error> <!-- works -->
> Voila! I can see field errors again.
> Just to summarize: To access a fieldError, I have to manually strip
> "form."from "form.email". I also have to set an additional ID on my form
> fields (with the stripped value) to be able to access it from my template.
> Is this the intended behaviour?
