Java – the trouble of iterating HashMap using JSF, myfaces, and facelets

I had some trouble looping through HashMap to print its values to the screen Someone can check my code carefully to see what I did wrong I can't seem to find any mistakes, but there must be something

In the servlet, I add the following to the request:

Map<String,String> facetValues = new HashMap<String,String>();
// Filling the map
req.setAttribute(facetField.getName(),facetValues);

In one case, "facetfield. Getname()" is evaluated as "discipline" So in my page, I have the following content:

<ui:repeat value="${requestScope.discipline}" var="item">
  <li>Item: <c:out value="${item}"/>,Key: <c:out value="${item.key}"/>,Value: <c:out value="${item.item}"/></li>
</ui:repeat>

Loop runs once, but all outputs are blank?!? If it's more than a loop, I'll expect at least something in the project Check the facelets debug pop-up window, where the discipline is and loop Printing it to the screen will produce some maps that look like me (I shortened the output):

{300=0,1600=0,200=0,...,2200=0}

I also tried C: for each, but I got the same result So someone has any idea. Did I make a mistake?

Thank you for any comments, leeward

Solution

< UI: repeat > only accept list or datamodel, not sets or maps This is the roadmap for JSF 2.1
