Suppress unsaved changes message in Cuba Platform

I have a lookup screen with authors and I load the data by using a custom query in init from AuthorsBrowse::AbstractLookup. I manipulate the data I want to display, but the changes should not be saved.

If I close the tab i get this message dialog:

You have unsaved changes Do you want to discard unsaved changes?

How can I suppress this message?

Solution

  • This message appears if anything datasource was changed.

    If you want suppress message, you need to add to datasource (that was changed) attribute allowCommit="false", like that:

    <collectionDatasource id="authorsDs"
                      class="com.haulmont.workshop.core.entity.Author"
                      view="_local"  allowCommit="false">
    <query>
        <![CDATA[
        select e from ws$Author e where e.status = 10
        ]]>
    </query>
</collectionDatasource>
