Hi.
I'm trying to implement Primefaces (version 5.1) using jdeveloper (version 11.1.2.4.0). This is the example i'm trying to implement: http://www.primefaces.org/showcase/ui/input/autoComplete.xhtml
I've been googling it around for the last 5 hours or so, but I still haven't solved my problem.
What did I do?
I created a new project from scratch and added the Primefaces library to both "Libraries and Classpath" and "Facelets Tag Libraries".
Then I created my view and 4 managed beans that represent the 4 classes that you can see in that example: AutoCompleteView, ThemeService, Theme and ThemeConverter.
Then I added the component to my view:
<?xml version='1.0' encoding='UTF-8'?>

</p:panelGrid>
</p:dialog>
</h:form>
</af:document>

</f:view>
My problem is in completeMethod="#{autoCompleteView.completeTheme}" because I get the warning "completeTheme is an unknown property".
In my completeTheme method, the service variable is always null, so I'm getting a null point exception.
| public List<Theme> completeTheme(String query) { |
| | |
| | List<Theme> allThemes = service.getThemes(); |
| | List<Theme> filteredThemes = new ArrayList<Theme>(); |
| | |
| | for (int i = 0; i < allThemes.size(); i++) { |
| | Theme skin = allThemes.get(i); |
| | if(skin.getName().toLowerCase().contains(query)) { |
| | filteredThemes.add(skin); |
| | } |
| | } |
| | |
| | return filteredThemes; |
| } |
Then I tried to initialize the service variable in my method, but I still don't have the expected results. I get "
<PprResponseWriter$PPRTag> <finish> no PPR-capable ID found for elements of: org.primefaces.component.autocomplete.AutoComplete@a0dbd2"
| public List<Theme> completeTheme(String query) { |
| | if(this.service==null){ |
| | FacesContext context=FacesContext.getCurrentInstance(); |
| | this.service=context.getApplication().evaluateExpressionGet(context, "#{themeService}",ThemeService.class); |
| | } |
| | |
| | List<Theme> allThemes = service.getThemes(); |
| | List<Theme> filteredThemes = new ArrayList<Theme>(); |
| | |
| | for (int i = 0; i < allThemes.size(); i++) { |
| | Theme skin = allThemes.get(i); |
| | if(skin.getName().toLowerCase().contains(query)) { |
| | filteredThemes.add(skin); |
| | } |
| | } |
| | |
| | return filteredThemes; |
| } |
So... can anyone help me please? I'm probably doing some n00b mistake since I've only been working with ADF for the last 2 weeks or so...
Thank you in advance.
