Is MultipleImageUploadEditorAttribute file missing? about serenity

[volkanceylan]

Actually you can use it with EditorType("MultipleImageUpload"), as editor type attributes are just intellisense helpers. But i'm not sure if multiple upload editor works properly, didn't use it for long time, need to have a look.

I tried EditorType attribute usage, editor shown properly but when updating record have an errror:

Error you are getting is because MultipleImageUploadEditor sends JSON array to server side by default as field value, and it can't be deserialized to a string field.

Please update Serenity nuget packages to 1.5.1.

I tried making sure MultipleImageUpload works properly in this version.

Then use the ImageUploadEditor attribute like below:

        [ImageUploadEditor(allowMultiple: true, JsonEncodeValue = true)]
        public String ProductImages { get; set; }

And on top of your SaveHandler you should use EmbeddedMultiFileUploadBehaviour instead of EmbeddedFileUploadBehaviour as below:

[EmbeddedMultiFileUploadBehaviour("ProductImages", fileNameFormat: "ProductImage/{1:00000}/{0:00000000}_{2}", copyFilesToHistory: true)]
private class MySaveHandler : SaveRequestHandler<MyRow> {
}

After this it should work.

I updated serenity packages. I can use ImageUploadEditor . There is no EmbeddedMultiFileUploadBehaviour attribute class. I used EmbeddedFileUploadBehaviour and normally get an error:

Failed to load resource: the server responded with a status of 404 (Not Found)
jquery-2.1.4.js?v=EH--lVW_yI7FyrUkx5D-NA2:8630 POST http://localhost:59837/File/TemporaryUpload 404 (Not Found)

Serenity.Web and Serenity.CodeGenerator 1.5.1 packages somehow didn't make it to Nuget gallery, try to update them again please, and rebuild project.

Please reopen this if problem still persists.
