Developing Custom component using TCOMP and the documentation simply doesn't work

konvertilo — Fri, 02 Jan 2026 14:45:42 GMT

I tested with older version, now it's 1.64.5 and still the problem persists :

- IntelliJ plugin : impossible to click the "NEXT" button" (java.lang.NullPointerException: Cannot invoke "org.talend.sdk.component.intellij.module.step.StarterStep$StarterPanel.getPanelLoaded()" because "this.starterPanel" is null). You will need to go through the starer kit on the website (it works now)

- For a very simple Processor, impossible to display the incoming schema in the Studio, at design time, in a tableau in order to configure the order of field for example, or add any configuration on a field level. you can have single field, String, Number, etc,

This below doesn't show in the UI :

@Option
@Documentation("Incoming metadata.")
@Structure(type = Structure.Type.IN)
private List<SchemaInfo> incomingSchema;

I'll wait for the version 1.65...

To add on top of this, I need to clarify : nothing in the document explain how to retrieve the incoming schema and populate a table that would be displayed during design time.

Someone from Talend team to give us some information on how to get the list of fields in design mode to build the configuration in design time ?...

Hélas, je me sens tout seul sur ce sujet. Je vais fermer dans quelques jours et trouver un autre moyen.
