Re: File upload stuck on loading
Thanks Craig for your response.
Sadly I can't change that part as too much treatment is happening on the
server side and data us being communiated as it is to the client.
Same issue happens if I comment the loader.load() then hit the refresh
button.[image: IMG_20221012_131516.jpg]

Yes we are using GXT 2.2.5 with GWT 2.8.1
We have a custom Grid object created that has an EditoGrid,
PagingToolbar, ListStore, ColumnModel and many other properties like
height..
I found that the problem is caused by the load method inside the
PagingLoader.
we have this line:
grid.reconfigure(store, grid.getColumnModel())
then the following line that causes the error:
loader.load(config).
config is a PagingLoadConfig
I tried loader.load() and loader.load(0.50) and
grid.getStore().getLoader().load()
but nothing seems to work.

It would certainly help if you provided details on how you do the
upload (using GWT's own FormPanel and FileUpload? or a third-party
library?
GXT-specific widgets?) and how you handle the response (including how you
generate it server-side)
For example, see the note at

about server-side requirements.

Re: File upload stuck on loading
I have no clue what your error is, but it's so much easier to read files
with HTML5 now.
Something like this:
-
@UiField InputElement fileInput;
Event.sinkEvents(fileInput, Event.ONCHANGE);
Event.setEventListener(fileInput, event -> handleFileUpload());
private void handleFileUpload() {
JavaScriptObject files = fileInput.getPropertyJSO("files");
if (files instanceof JsArray) {
JsArray filesArray =
(JsArray)files;
if (filesArray.length() > 0) {
handleFileUploadJS(filesArray.get(0), fileData ->
handleAfterFileUpload(fileData));
}
}
}
private static native void handleFileUploadJS(JavaScriptObject fileData)
/*-{
var fileReader = new FileReader();
fileReader.addEventListener("load", function () {
// Your file data will be in fileReader.result
}, false);
fileReader.readAsDataURL(fileData);
}-*/;
-
No server code needed. :)

The list is received as it is, we have a method that will fill the grid
with that list but somethiing is stopping it. It still print a loading
spinner that never stops.
The same code works well with gwt 2.4/gxt 2.2.5.
Now we are using gwt 2.8/gxt 2.2.5
