----------------------------------
Resolution: Resolved
> [Wicket Viewer] Support for TitleColumn Header Translation
> ----------------------------------------------------------
>
> Key: CAUSEWAY-4003
> URL: https://issues.apache.org/jira/browse/CAUSEWAY-4003
> Project: Causeway
> Issue Type: Improvement
> Components: Viewer Wicket
> Affects Versions: 4.0.0-M1
> Reporter: Miklós Győrfi
> Assignee: Andi Huber
> Priority: Minor
> Fix For: 3.7.0, 4.0.0
>
>
> In the Apache Causeway Wicket Viewer component, the {{TitleColumn}} (used to
> display the first/primary title column in parented and standalone collections
> inside {{{}CollectionContentsAsAjaxTablePanel, etc.{}}}) hardcodes the column
> headers as English text strings ("Object" and "Related Object").
> Because this is evaluated via a static helper method during constructor
> invocation, it bypasses the framework's translation mechanisms, making it
> impossible to localize these headers via standard {{translations.po}} files.
> *Affected Class:*
> {{org.apache.causeway.viewer.wicket.ui.components.collection.present.ajaxtable.columns.TitleColumn}}
> *Current problematic code snippet:*
>
> {code:java}
> private static String columnName(
> final @Nullable Variant variant,
> final int maxTitleLength) {
> if(maxTitleLength == 0) {
> return "";
> }
> return (variant.isParented() ? "Related ":"") + "Object"; // <--
> Hardcoded English Strings
> }
> {code}
>
> *Proposed Solution / Fix:*
> The {{columnName}} method should dynamically resolve the text using
> Causeway's {{TranslationService}} fetched from the {{MetaModelContext}} to
> allow proper localization.
> {code:java}
> private static String columnName(
> final @Nullable Variant variant,
> final int maxTitleLength) {
> if(maxTitleLength == 0) {
> return "";
> }
> String defaultLabel = "Object";
> String contextClass = TitleColumn.class.getName();
> var mmc = MetaModelContext.instanceNullable();
> if (mmc != null) {
> TranslationService translationService =
> mmc.getTranslationService();
> if (translationService != null) {
> var translationContext =
> TranslationContext.named(contextClass);
> if (variant != null && variant.isParented()) {
> return translationService.translate(translationContext,
> "Related Object");
> } else {
> return translationService.translate(translationContext,
> "Object");
> }
> }
> }
> return (variant != null && variant.isParented() ? "Related " : "") +
> defaultLabel;
> }
> {code}
