Uncaught TypeError: Cannot read property 'comboBox' of undefined

@gatanaso Hello! I managed to run it, I had to change the version of Vaadin in the project. And yeah it works in latest versions.

Hi @onuridrisoglu

Thank you for reporting this issue. It would appear that a similar issue exists if you replace the MultiselectComboBox with a ComboBox (and update the example to work):

ComboBox roleSelector = new ComboBox();
roleSelector.setItems("User", "Admin");

In which case you get comboBoxConnector.js?c659:250 Uncaught (in promise) TypeError: Cannot read property 'overlay' of undefined

I suspect the underlying issue lies with the GridPro and the way it is attaching the components, though I have not investigated further.

yes, but the problem with multiselect-combo-box is dataProvider cannot initialise after this error, where as combo-box works fine

[gatanaso]

Thanks for providing more details @onuridrisoglu 🙏 I will look into it.

Hello! Any progress?

Hi @Me1kaa,

This is a side-project for me and unfortunately I haven’t had much time to work on it due to customer projects. I will give it a look as soon as I have more time on my hands.
