This is the set-up: a document belongs to a category. Category is a class with an ID (Integer - auto generated), a name and a description. One category can have many documents.
A data table of documents is displayed. The category is in a selectOne and the name is displayed. This is what it looks like in the view:
<h:selectOneMenu id="category" value="#{document.category.categoryID}" required="true">
<f:selectItems value="#{categorySessionBean.categoryList}" />
</h:selectOneMenu>
This is what an f:selecItem looks like:
categoryList = new SelectItem[categories.size()];
int i=0;
for(Category cat:categories){
categoryList(i)=new SelectItem(cat.getCategoryID(), cat.getName());
i++;
}
The () after categoryList should be square brackets. It is seen as formatting and ignored.
I've tried s:selectItems and it doesn't work for me. I get and "invalid value" when trying to do an update with it. Maybe the place holders have something to do with it.
How can I use a selectOne to change the category of a document? The display is right, the xhtml code is right, just it does not work.
Any help will be greatly appreciated.
