Return of older bug. Cannot update Dataset

[Solomin0]

Describe the bug

@abidlabs
Unable to update the dataset object correctly. It seems like all the threads on this are closed or before 4.0 using the old .update methods.
#2143
Any help or workarounds would be great thanks.

Reproduction

import gradio as gr
def update(name):

    print(name)
    # new_examples = gr.Examples(["1","2","3"], inputs=[inp],label = "Saved Prompts")
    # return f"Welcome to Gradio, {name}!", new_examples
    return [["a"],["b"]]
with gr.Blocks() as demo:
    with gr.Row():
        inp = gr.Textbox(placeholder="What is your name?")

        saved_examples = gr.Dataset(components = ["text"], samples = [["This is my Favorite Prompt"]],label= "Saved Prompts" )

        saved_examples.click(update, inputs=[saved_examples], outputs=[saved_examples])
    # btn.click(fn=update, inputs=inp, outputs=[ex])

I can work around it

Hi @Solomin0 according to your code I guess you are trying to build a simple UI that can save input text as examples for future use. In that case you can try this code:

import gradio as gr

examples = []

def update(input):
    examples.append([input])
    return examples

def fill_input(index):
    return examples[index][0]

with gr.Blocks() as demo:
    with gr.Row():
        inp = gr.Textbox(placeholder="What is your name?")

        saved_examples = gr.Dataset(components = ["text"], samples = examples,label= "Saved Prompts", type = "index")
        btn = gr.Button("Save Prompt")

    saved_examples.click(fill_input, inputs=[saved_examples], outputs=[inp])
    btn.click(fn=update, inputs=[inp], outputs=[saved_examples])
    # btn.click(fn=update, inputs=inp, outputs=[ex])

demo.launch()
