Did you look
at ./src/java/org/apache/lenya/cms/site/usecases/Overview.java?
There you find:
...
Version latestVersion = workflowable.getLatestVersion();
Boolean isLive = null;
if (latestVersion != null) {
setParameter(STATE, latestVersion.getState());
if
(Arrays.asList(variableNames).contains(WORKFLOW_VARIABLE_ISLIVE)) {
isLive =
Boolean.valueOf(latestVersion.getValue(WORKFLOW_VARIABLE_ISLIVE));
}
} else {
setParameter(STATE, workflow.getInitialState());
if
(Arrays.asList(variableNames).contains(WORKFLOW_VARIABLE_ISLIVE)) {
isLive =
Boolean.valueOf(workflow.getInitialValue(WORKFLOW_VARIABLE_ISLIVE));
}
}
setParameter(ISLIVE, isLive);
Could you not reuse that?
