Creating DOM Elements on the fly ! (ManagedInstance<T extends JavaScriptObject>)

[mjm.ent]

How does one create native DOM elements on the fly ?

ManagedInstance<T> works as expected for user defined @Templated objects. But while DOM dependencies are resolved using a simple @Inject of the same class, as far as I can tell, ManagedInstance cannot resolve dependencies for native JavaScriptObjects or DOM elements.. Example :

@Inject

private Image image; // Works as expected

@Inject

private ManagedInstance<Image> image; // Results in "Multiple beans matched com.google.gwt.core.client.JavaScriptObject$ with qualifiers { javax.enterprise.inject.Default }"

Elements can be created using the GWT API, example :

DOM.createElement("img)

new Image("/img/source.jpg"))

However there appears to be a inherent incompatibility between the GWT API and the Errai API.

Is this functionality supported, what is the correct syntax ?

Hi Mathieu,

Unfortunately, as you've discovered, GWT does not generate classes for JavaScriptObjects the same way it does for normal Java types. This breaks dynamic lookup of any types extending JavaScriptObject.

Currently we have no solution for this. I'd recommend creating a factory class that you can inject (ex. ImageFactory) that uses the DOM or GWT API to create elements.

Cheers.
