ListWidget and binding

[magick93]

Hi

I have a list widget - RuleListWidget - and this is to get its list of rules from a service call response.

My struggle is - how do I get my list of rules into the RuleListWidget?

I'm setting the items at @PostConstruct - which does seem wrong - but what should I do?

ruleService.call(new RemoteCallback<List<app.client.shared.datamodel.Rule>>() {


                                                            @Override
                                                            public void callback(List<app.client.shared.datamodel.Rule> response) {                                                                      
  
                                                                      rulesWidget.rules=response;
                                                                      rowContainer.add(rulesWidget);    
                                                             }).getRules();

package app.client.local;


import java.util.List; 

import javax.annotation.PostConstruct; 

import org.jboss.errai.ui.client.widget.ListWidget;

import app.client.shared.datamodel.Rule;


public class RuleListWidget extends ListWidget<Rule, RuleWidget> {
  
          List<Rule> rules;
  
          @PostConstruct
            public void init() { 
             this.setItems(this.rules);
            }


          @Override
          protected Class<RuleWidget> getItemWidgetType() {
                    return RuleWidget.class;
          }


}

Hi Anton,

You don't need to extend the ListWidget to use it. There is a producer that can produce differenent list types: OrderdList, UnOrderdList or a Generic one if you don't specify a qualifier.

Below an example:

{code}
@Inject      //will create a new listwidget for you
@DataField
@OrderedList      //orderd list
ListWidget<Rule, RuleWidget> rules;
...
    @PostConstruct
    public void buildWidget() {
     ruleService.call(new RemoteCallback<List<app.client.shared.datamodel.Rule>>() {
                                                            @Override
                                                            public void callback(List<app.client.shared.datamodel.Rule> response) {                                                                      
                                                                      rules.setItems(response);
                                                                      rowContainer.add(rulesWidget);    
                                                             }).getRules();
    }
{code}

Hope that helps,

Hi Erik

I have upgraded to 2.4 beta1, primarily to take advantage of your work on lists.

Its a very elegant way of working with lists - nice work!

I have a few questions:

Is there documentation yet on this feature?

In a template, should I add the <ul> tags or does Errai do that?
