我在Primefaces 6的對話框中有一個p:消息,但是此元素沒有與任何內容一起顯示。它只是不顯示在屏幕上。我在bean中設置錯誤消息,但它不顯示消息。我想要在對話框中顯示錯誤消息。我嘗試更新commandbutton和Bean中的p:messages。下面是代碼:p:在primefaces中對話框中沒有顯示的消息
豆:
public void persist() {
boolean error = false;
addErrorMessage("schedule_summary_error_message", "FUMBLE! Something went wrong! Try it again.", null); // Added this line so the error message can show no matter what but it still doesn't show.
for (int i=0; i < newMatchups.size(); i++) {
if (!matchupService.persist(newMatchups.get(i)))
error = true;
}
if (error) {
addErrorMessage("schedule_summary_error_message", "Something went wrong! Try it again.", null);
} else {
reloadCurrentMatchups();
RequestContext.getCurrentInstance().execute("PF('newScheduleDialog').hide()");
}
}
private static void addErrorMessage(String clientId, String summary, String detail) {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(clientId, new FacesMessage(Constant.ERROR, summary, detail));
}
XHTML:

position="center top" closeOnEscape="true" width="60%" modal="true" style="overflow-y:auto;max-height:100%">

剛剛嘗試過,但沒有奏效。該消息仍然不顯示。我添加這個p:messages的原因是當我們遇到數據庫事務中的異常或任何其他異常時,顯示錯誤消息。 – flacoding
