I just upgraded from GWT 2.8.0 to 2.8.2 and get a class cast exception
which I don't understand, please some help.
It goes wrong in the following line of code:
*ZtoeslagAppConfig this.bla = new
JsoZtoeslagAppConfig(getZtoeslagConfig());*
All relevant code:
*private <T extends JavaScriptObject & ZtoeslagAppConfig> T
getZtoeslagConfig() {*
* return (T) UtilsJsni.getProperty(getJson(),
getMiscValues().zorgtoeslag());*
*}*
*private JavaScriptObject getJson() {*
* return this.json;*
*}*
*public interface ZtoeslagAppConfig {*
* AppPage[] getPages();*
*}*
*public final class JsoZtoeslagAppConfig implements ZtoeslagAppConfig {*
* private final JavaScriptObject jsoConfig;*
* public <T extends JavaScriptObject & ZtoeslagAppConfig>
JsoZtoeslagAppConfig(final T jsoConfig) {*
* super(jsoConfig);*
* }*
* public AppPage[] getPages() {*
* return UtilsJsArrays.toArray(getJsoPages());*
* }*
* private JsArray<? extends JsoAppPage> getJsoPages() {*
* return UtilsJsni.getPropertyAsArray(getJsoConfig(),
getMiscValues().pages());*
* }*
* private JavaScriptObject getJsoConfig() {*
* return this.jsoConfig;*
* }*
*}*
During super dev mode, in Chrome the values of this.json above:
*json_1_g$:*
* newsletter: "825eceb44f"*
* zorgtoeslag: {payments: Array(3), pages: Array(3)} *
Just before calling the constructor in:
*new JsoZtoeslagAppConfig(getZtoeslagConfig());*
It is calling a gwt method for casting that seems to fail:
* static Object castTo(Object src, JavaScriptObject dstId) {*
* checkType(src == null || canCast(src, dstId));*
In this method, I see that dstId has the value 1891, and src is some json
value.
When performing the above body it calls the following method, that I don't
directly understand as I don't see the method call in the above function:
* static native boolean jsEquals(Object a, Object b) /*-{*
* return a == b;*
* }-*/;*
I think this method fails as a is some json and b has the value null.
What goes wrong here?
