Entity snapshot view and REST API

Support
#1

Hello,

I have 2 questions regarding the entity snapshots:

Question 1:
I tried to reproduce what is described here:

https://doc.cuba-platform.com/manual-7.2/manual.html#entity_snapshots_view

I tried to change to adapt the code to be 7.X, and did this:

On the screen controller:

    @Subscribe
    public void onAfterShow(AfterShowEvent event) {
        if (!entityStates.isNew(sessionDc.getItem())) {
            diffFrame.loadVersions(sessionDc.getItem());
        }
    }

On the screen designer:

        <tabSheet>
            <tab id="versionsTab"
                 caption="Versions"
                 margin="true,false,false,false"
                 spacing="true">
                <frame id="diffFrame"
                               src="/com/haulmont/cuba/gui/app/core/entitydiff/diff-view.xml"
                               width="100%"
                               height="100%"/>
            </tab>
        </tabSheet>

However, I couldn’t manage to have a proper rendering in the UI:

I can see the 2 snapshots of my entity, but the area on the right remains empty:

Am I missing something ?

Question 2:
Is it possible to expose the snapshots through the REST API if I create a dedicated service ?

Thanks in advance !

Hi.
Thank you for reporting the problem. We have created a GitHub issue.

You can find information about working with service in REST API here.
