Re: T5:how to do initialization work when custom component was
called?
Hi cleverpig,
You can use @SetupRender or onActivation methods to setup ur page.
There was a long discussion in the mail list about when to use what.
Using the @setuprender on ur page would be as simple as:
@SetupRender
private void loadData() {
this.data=serv.list();
}
