Re: Having trouble with UiBinder renderer

Ok many thanks Thomas for the help,

So I'll try to put a variable of type SafeUri to <img src={safeUri}"> I thought that since the method accepts a String in src, it would need another attribute for the SafeUri

May I suggest to put it all together in a different documentation than the one for uiBinder (example in UiRenderer): Indeed I've read that page, and since it is somewhere in the resources, I skipped it. I know that in the code it's related (UiBinder, UiRenderer, eventually ClientBundle), but conceptually as a user I perceive those things as separate enough to be in different sections (naturally it's only my point of view as an old GWT user, that saw the things being added gradually. I think, it could be confusing for a newbie to see UiBinder in the same section as UiRenderer)

Anyway, thanks for the help, I'm glad I'm able to keep going :)

Hi All,

I'm trying to use a UiBinder like this

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder">
 <ui:with field='logo' type='java.lang.String' />
 <ui:with field='name' type='java.lang.String' />
 <ui:with field='desc' type='com.google.gwt.safehtml.shared.SafeHtml' />
 <ui:with field='prodCnt' type='java.lang.String' />
 <div class="shopMainCell">
 <div class="shopLogo">
 <img src='{logo}' />
 </div>
 <div class="shopProps">
 <div class="name">
 <ui:text from='{name}'></ui:text>
 </div>
 <div class="desc">
 <ui:text from='{desc}'></ui:text>
 </div>
 <div class="prodCnt">
 <ui:text from='{prodCnt}'></ui:text>
 </div>
 </div>
 </div>
</ui:UiBinder>

But I receive two errors:

• java.lang.String required, but {desc} returns com.google.gwt.safehtml.shared.SafeHtml: <ui:text from='{desc}'> 
  

And I know there is no <ui:safeHtml> possible tag

Actually, yes, there is; it's all lowercase though: <ui:safehtml from="{desc}" />

http://www.gwtproject.org/doc/latest/DevGuideUiBinder.html#Hello_Html_Resources

 

• Escaping unsafe runtime String expression used for URI with UriUtils.fromString(). Use SafeUri instead: <img src='{logo}'> (:9)
  

What? weren't it complaining it doesn't support a SafeHtml?

No, it was saying that <ui:text from=""/> expects a String (just like it would for a toto="" attribute corresponding to a setToto(String) setter);

but <img src=""/> is known to be a URI reference so it warns when it's not a SafeUri (similarly it would warn for style="{s}" if s is not a SafeStyles)
