Hi,
I have a problem in visualization for not persistence Entity in a table,
Entity (Info.java):
MetaClass(name = “app_Info”)
public class Info extends AbstractNotPersistentEntity implements Versioned, SoftDelete, Updatable, Creatable {
MetaProperty
protected String version;
MetaProperty
protected String data;
}
Descriptor (info-browse.xml):
<data readOnly=“false”>
<collection id=“infosDc” class=“app.entity.Info” view="_local">
</collection>
</data>
…
<table id=“infosTable” width=“100%” dataContainer=“infosDc”>
<columns>
<column id=“version”/>
<column id=“data”/>
</columns>
Controller (InfoBrowse.java):
UiController(“app_Info.browse”)
UiDescriptor(“info-browse.xml”)
LookupComponent(“infosTable”)
LoadDataBeforeShow
public class InfoBrowse extends StandardLookup {Subscribe
public void onInit(InitEvent event) {
Info infoMacchina = dataManager.create(Info.class);
infoMacchina.setVersion(“Testttt”));
infoMacchina.setData(“1212”);
infosDc.getMutableItems().add(infoMacchina);
}
}
}
In debug I can see that when I try
infosDc.getMutableItems().add(infoMacchina);
I have the following error:
