Array in @ExtDirectMethod

[salamoun]

Is it possible to send array over simple named method??
For example:

@ExtDirectMethod(ExtDirectMethodType.SIMPLE_NAMED)
public void sendSomeData(List objects, int someId) {
...
}

Hi

Yes it looks like it works. I made a quick test with this client code:

var values = {
aLotOfStrings: ['a', 'b', 'c'],
firstName: 'first',
lastName: 'last',
age: 27
};
namedService.showDetails(values, function(value){
Ext.example.msg('Server Response', value);
});

and this server code:

@ExtDirectMethod(value = ExtDirectMethodType.SIMPLE_NAMED, group = "named")
public String showDetails(List aLotOfStrings, String firstName,
String lastName, int age) {
for (String string : aLotOfStrings) {
System.out.println(string);
}
return String.format("Hi %s %s, you are %d years old.", firstName,
lastName, age);
}

OK, but I'm not sending array of string. I have array of bussines objects.

var myObjects = [{id:1,name:'test'},{id:2,name:'test2}];

Is it possible too? Because I got spring conversion error in this case.

Here the missing stacktrace:

[salamoun]

yes, i get exactly same error

[ralscha]

Found a solution that works with my simple test case. I try and integrate the fix into the 'next' branch (1.2.3-SNAPSHOT) tomorrow. I keep you posted.

[salamoun]

OK, thanks for help.

[ralscha]

Fix is now integrated in the lastest 1.2.3-SNAPSHOT Release.
https://oss.sonatype.org/content/repositories/snapshots/ch/ralscha/extdirectspring/1.2.3-SNAPSHOT/extdirectspring-1.2.3-20121121.035026-8.jar

Maybe you have time and test this release with your program.
If all goes planned I will release the 1.2.3 version end of November.

It's important that the business object has a default constructor. The jackson library needs this to deserialize the object. The method also has to use generics:
public void sendSomeData(List<BusinessObject> objects, int someId) {

If the method only has a raw list as parameter it will work but the list then contains a map with String key and Object values.
public void sendSomeData(List objects, int someId) {

[salamoun]

I test it and now works perfect with 1.2.3 version!

But it has side effect. I previously use version 1.1.1. When I switch to 1.2.3 I must update all my JSON annotations on business object, otherwise they were ignored.
From import org.codehaus.jackson.annotate.* to import com.fasterxml.jackson.annotation.*.
New versions of extdirectspring use com.fasterxml.jackson serialiazer?? Or I'm doing something wrong?

[ralscha]

Hi

We switched to Jackson 2 in version 1.2.0 and they changed the package
structure.
Is this a problem in your project? If yes I could try and add this fix in
version 1.1.x

No, I change import to new packages and all code works fine. Thanks!
