I actually figured something out to make it work but I am curious if I
am using it correctly.
Here is the code that I am using to setup the store:
-------------
final RecordDef recordDef = new RecordDef(new FieldDef[]{
new IntegerFieldDef("id"),
new StringFieldDef("title"),
new StringFieldDef("description"),
new StringFieldDef("skill"),
new StringFieldDef("nationality"),
new StringFieldDef("dishtype"),
new IntegerFieldDef("servings"),
new StringFieldDef("author"),
new DateFieldDef("created_at", "created_at",
"timestamp")
});
JsonReader reader = new JsonReader(recordDef);
reader.setRoot("recipe");
// reader.setId("id");
DataProxy dataProxy = new ScriptTagProxy("http://localhost/
recipevault_feed/getrecipe.php");
final Store store = new Store(dataProxy, reader, false);
StoreListenerAdapter listenerAdapter = new StoreListenerAdapter
() {
public void onLoad(Store store, Record[] records) {
loadForm(store);
}
};
----------
Then I have this code for the "load" button:
-------------
final Button loadBtn = new Button("Load", new
ButtonListenerAdapter() {
public void onClick(Button button, EventObject e) {
store.load();
GWT.log("store size "+store.getCount(),null);
submitBtn.enable();
}
});
...
}
private void loadForm(Store store) {
try {
this.getForm().loadRecord(store.getRecordAt(0));
} catch (Exception ex) {
GWT.log("loadForm(Store store)", ex);
}
}
-------------
I figured out that I needed to load the form from the Store listener
onLoad(). Does that seem correct?
>From my attempts at debugging, the store would be empty after calling
store.load() the first time. But, then when I would hit the load
button again, the store would have information in it.
