Re: How to implement loops in render method of new UiRenderer feature

Hi,

You can use <ui:safehtml from='{...}'/> in your uiRenderer template.

  <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder">    <ui:with field='name' type='java.lang.String' />    <ui:with field='itemsHtml' type='com.google.gwt.safehtml.shared.SafeHtml'/>    <div id="main">      <h2><ui:text from='{name}' /></h2>      <div><ui:safehtml from='{itemsHtml}'/></div>    </div>  </ui:UiBinder>  

Generate your SafeHtml (with SafeHtmlBuilder, SafeHtmlTemplates or UiRenderer) and give it to renderer. For exemple :

  public void render(Context context, EntityProxy e, SafeHtmlBuilder sb) {    SafeHtmlBuilder itemsShb = new SafeHtmlBuilder();    for (Item item : e.getItems()) {      itemsShb.appendHtmlConstant("<span>").appendEscaped(item.getName()).appendHtmlConstant("</span>");    }    SafeHtml itemsHtml = itemsShb.toSafeHtml();    renderer.render(sb, e.getName(), itemsHtml);  }

Hi there,

 I know that gwt templates don't support loops.

However, I'd like to have a loop in a render() method.

Let's say I have this simple UiRenderer template:

<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder">

<ui:with field='name' type='java.lang.String' />

        <div id="main">

            <h2><ui:text from='{name}' /></h2>

            <div id="HERE"></div>

        </div>

</ui:UiBinder>

What I need to do is put some new code into div#HERE from render method. Something like:

public void render(Context context, EntityProxy e, SafeHtmlBuilder sb) {

renderer.render(sb, e.getName());

                for(Item item : e.getItems()) {

                        String s = "<span>"+item.getName()+"</span>";

                        //How to put every s from this loop  into div#HERE ?

                 }

}

Obviously, this can be done in traditional way without templates. I'm just wondering if it is possible with new UiRenderer.

Thanks,

Peter
