Hope that helps When you disable a component, the disabled state is handled both on the client and the server side, meaning, a component isn't just visually disabled, but the server also refuses to handle any requests to a disabled component.
The warning you are seeing means, that there is an RPC request (HTTP request from the client-side) that is targeted for a disabled component. Since the component is disabled, the RPC request will be ignored.

seems to work fine The problem was that I should change the repository because I want to use a prerelease version. To do this the below lines should be added to repository in pom file:
code :
<pluginRepositories>
    <pluginRepository>
        <id>vaadin-prereleases</id>
        <name>Vaadin Pre-releases</name>
        <url>https://maven.vaadin.com/vaadin-prereleases</url>
    </pluginRepository>

</pluginRepositories>
<repositories>
    <repository>
        <id>vaadin-prereleases</id>
        <name>Vaadin Pre-releases</name>
        <url>https://maven.vaadin.com/vaadin-prereleases</url>
    </repository>
    <repository>
        <id>vaadin-addons</id>
        <url>http://maven.vaadin.com/vaadin-addons</url>
    </repository>

I hope this helps . My problem was the vaadin.servlet.heartbeatInterval property in the application.properties. Looks like the correct name is vaadin.heartbeatInterval. After changing the property name everything works as expected.
