How to call the remote store for combobox in extjs v7.5?

Question

I have a combobox with data downloaded from a remote server. I want a request to be sent every time I click on the combobox, because I want to dynamically set parameters in proxy.setExtraParams(params). I set params in beforeQuery function. I have this example that I found on the Internet. In my application, the combo works in a similar way. https://fiddle.sencha.com/#fiddle/3ij5&view/editor

However, it works fine in version 7.4 and does not work in version 7.5.

The documentation for 7.5 says that when queryMode: 'remote' you have to manually load the store. Where do I call store.load() so that the combo has time to process the parameters for the proxy?

You have to set the autoLoad to true.

Because you do not want to load the store initially, you have to add a listener (as you did) and set the autoLoad.

You just want to call the listener once, because after that the autoLoad is set.

        listeners: {
            beforeQuery: {
                fn: function (queryPlan) {
                    console.log('[ComboBox::beforeQuery] set autoLoad to true');
                    this.getStore().setAutoLoad(true);
                    return queryPlan;
                },
                single: true
            }
        }
