GWT 2.8.0
I am pulling my hair out with this error. Hoping someone can help. I am
calling a Java method (in a GWT class) from an external javascript file.
I've done this without issue with several other java calls. However, when
I make the call from javascript to GWT and try to pass any parameters from
javascript to the GWT method via JSNI, I get a cryptic error that I am
unable to trace.
Javascript function (used this same pattern on multiple occasions without
issue)
function openJobDetailsDialog(){
this.displayJobDefinitionDialog("1", "2", "3");
}
GWT methods:
public native void displayJobDefinitionDialog(String jobId, String jobType,
String serviceId) /*-{
$wnd.displayJobDefinitionDialog =
$entry(@com.function.operation.Class::handleJobDefinition(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)(jobId,
jobType, serviceId));
}-*/;
public static void handleJobDefinition(String jobId, String jobType, String
serviceId) {
if(jobId != null) {
MessageDialog.MessageOk("", "handleJobDefinition for jobId: " + jobId + "
jobType: " + jobType + " serviceId: " + serviceId, null); //utility
method to help with debugging
//other logic here......
}
}
If I remove the parameters (Ljava/lang/String;) from the the
handleJobDefinition() method, it gets called fine and the MessageDialog
utility class displays the message I expect to see. Adding the parameters
to the calls does NOT result in a compile error. However, after adding the
parameters to the calls, I see the following at runtime:
com.google.gwt.core.client.JavaScriptException: (TypeError) : Cannot read
property 'apply' of undefined
=>Unknown.apply_0() at com.function.operation.tes.TES-0.js[-1]
=>Unknown.entry0_0() at com.tidalsoft.webclient.tes.TES-0.js[-1]
=>Unknown.anonymous() at com.tidalsoft.webclient.tes.TES-0.js[-1]
=>Unknown.openJobDetailsDialog() at
http://localhost:8081/client/businessViews.js[-1]
I've tried removing the "$wnd.displayJobDefinitionDialog =" from the
displayJobDefinitionDialog call and while that does compile, I get an error
indicating that the function cannot be found (which makes perfect sense).
The GWT documentation is a little sparse in this area.
Any help is greatly appreciated.
