dynamic dropdownlist alloyui

[Arnold Kevin Wenger, modificado hace 9 años.]

Hi,
I’m trying to make a dynamic dropdownlist.
I create a list of strings in my java class.
That list need to be send to my portlet preferences and fill up a dropdownlist and when I select a value it needs to be saved.
So that i can use the value in the future(cross user)
Biggest problem this point is how to fill that dropdown list.
Any idea's?

	
	public List<string> generateList(ActionRequest actionRequest, ActionResponse actionResponse)
	{
		ServiceContext serviceContext = null;
		try {
		serviceContext = ServiceContextFactory.getInstance(Group.class.getName(), actionRequest);
		} catch (PortalException | SystemException e2) {
			// TODO Auto-generated catch block
				e2.printStackTrace();
		}		
		
		//Filling the layout(template) list. 
		List<layoutsetprototype> layoutSetPrototypes = null;
		try {
			layoutSetPrototypes = LayoutSetPrototypeServiceUtil.search(serviceContext.getThemeDisplay().getCompanyId(),Boolean.TRUE, null);
		} catch (PortalException | SystemException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		LayoutSetPrototype layoutSetPrototype = null;
		
		List<string> Layoutnames = null;
		
		for(int index = 0; index &lt; layoutSetPrototypes.size(); index++)
		{
			layoutSetPrototype = layoutSetPrototypes.get(index);
			Layoutnames.add(layoutSetPrototype.getName());		
		}
		return Layoutnames;
	}
</string></layoutsetprototype></string>

Example how to get list of countries to the drop down.
same way you have to get list of values and you have to iterate using for each loop.
<c:set value="<%= countryId %>"/>
<aui:select name="countryId" id="countryId" label="" inlineField="true" >
<c:forEach items="${countries}" var="lstType">
<c:choose>
<aui:option value="${lstType.countryId}" selected="true"> ${lstType.name} </aui:option>

</c:choose>
</c:forEach>
</aui:select>
