Action Sequences Example (Obsolete)

Let's declare the model that we're going to use in this example:

@ServerModel(
    baseUrl = "http://example.com/",
    post = "/data?query={query}",
    model = "this"
)
@EBean
public class UploadData {
    String data;
    int successful;
    
    public void isSuccessFul() {
       return successful==1;
    }
}

In this example, when a button with Id btnUpload is pressed, a Modal named uploadData is put to upload data to a server, sending query=all . After the upload, in the UI Thread, it is tested isSuccessful() method to check if the Data was successfully uploaded and display a Toast depending of it.

@Model(lazy=true)
UploadData uploadData;

@Action({
    "message=\"Uploading Data\" -> :uploadingDialog",
    "query=all $uploadData",
    "ui: ;savingDialog.dismiss() -> uploadData.isSuccessful()?? -> Data uploaded successfully"
    "An error occurred while uploading the data"
})
S4<ProgressDialog, PutModel, Toast, Toast> btnUpload;

See that by default, putting a model will be executed asynchronously in a background Thread, because of it, before showing the Toast we change to the UI Thread starting the declaration with "ui" because a Toast can be shown only in the UI Thread, if not an exception will be thrown.
