One-to-one editing on the same screen

Support
#1

Hi,

I’m trying to edit a one-to-one relationship on the same screen. What I have mostly seems to work fine.

I have a datasource setup like this.

<dsContext>
    <datasource id="matterDs"
                class="com.zynde.tangmere.entity.matter.Matter"
                view="matter-create-view">
        <datasource id="contextDs"
                    property="context"/>
    </datasource>
</dsContext>

I have the initNewItem setup like this.

@Override
protected void initNewItem(Matter item) {
    super.initNewItem(item);

    item.setContext(metadata.create(MatterContext.class));
}

So all the above works nicely when Creating a new Matter Entity and Editing a Matter Entity that has a Context Entity created.

What doesn’t work is if I go to edit a Matter entity that doesn’t have a Context entity yet. So what is the best way to create a Context Entity when there isn’t one and I’m in the Edit Action of the Owner Entity?

Thanks

Hi,

You can use the postInit method and make all the nessesary checks. For instance, you can check if there is a Context entity or if the creating Matter entity is new using the com.haulmont.cuba.core.global.PersistenceHelper#isNew method.
