Component does not work together with vaadin-combo-box-flow

[symVmueller]

Issue:
When using multiselect-combo-box-flow in a project with vaadin-combo-box-flow apparently there is a problem whilst building the frontend with webpack. The Build is successful, but results in most of the used webcomponents throwing Errors.
For example:

• undefined connectors for various components (context menu, select, grid, ...)
• unsupported operation in vaadin-combo-box-item.js:178

Expected:
No errors and working components when using vaadin-core components with multiselect-combo-box-flow

Sidenote:
This might be a vaadin-flow issue, but since i'm not sure about that it is posted here.

Hi @symVmueller

I believe the issues were caused by conflicting dependencies that were being pulled in by the web component. I have updated the flow integration and published a new release candidate version compatible with Vaadin 14:

<dependency>
   <groupId>org.vaadin.gatanaso</groupId>
   <artifactId>multiselect-combo-box-flow</artifactId>
   <version>2.0.0.rc2</version>
</dependency>

Please give it a try and let me know if there are any issues.

BR,
Goran
