[jira] Commented: (TRB-9) Intake: Handling of empty values
[ http://issues.apache.org/jira/browse/TRB-9?page=comments#action_12417306 ]
Jürgen Hoffmann commented on TRB-9:
-----------------------------------
This patch also addresses the issue of intake, not being able to use default validators i.e. BooleanValidator, if the rules are empty.
> Intake: Handling of empty values
> --------------------------------
>
> Key: TRB-9
> URL: http://issues.apache.org/jira/browse/TRB-9
> Project: Turbine
> Type: Bug
> Components: Turbine 2.3
> Versions: Core 2.3.2
> Reporter: Stefan Broetz
> Priority: Blocker
> Attachments: patch_TRB-9.txt
>
> It seems to be impossible transmit the empty string as a value: In the HTTP request
> http://.../turbine/...?aaa=123&bbb=&ccc=456
> the parameter bbb is ignored.
> If you look at org.apache.turbine.services.intake.model.Field.init(ValueParser pp) you find:
> if (pp.containsKey(getKey()))
> {
> if (isDebugEnabled)
> {
> log.debug(name + ": Found our Key in the request, setting Value");
> }
> if (StringUtils.isNotEmpty(pp.getString(getKey())))
> {
> setFlag = true;
> }
> validate();
> }
> else if (pp.containsKey(getValueIfAbsent()) &&
> pp.getString(getValueIfAbsent()) != null)
> {
> pp.add(getKey(), pp.getString(getValueIfAbsent()));
> setFlag = true;
> validate();
> }
> The StringUtils.isNotEmpty() condition (line 342) prevents that a field can take up the empty string as its value.
