xtext_2.8.4.v201508050135.version:

I tried the suggestions from https://www.eclipse.org/forums/index.php/mv/msg/297566/870958/#msg_870958, (from 2012), but got an error:

0 [Worker-7] ERROR org.xtext.example.mydsl.ui.internal.MyDslActivator - Failed to create injector for org.xtext.example.mydsl.MyDsl

Before, I got an error for the @override annotation in the

public class MyDslUiModule extends org.xtext.example.mydsl.ui.AbstractMyDslUiModule {
public MyDslUiModule(AbstractUIPlugin plugin) {
super(plugin);
}
@Override
public Class<? extends ITemplateProposalProvider> bindTemplateProposalProvider() {
return MyTemplateProposalProvider.class;
}
}

So I assume something has changed in the internals of xtext. Perhaps someone can give me a hint what to do to adjust the code; the navigation in the templates is just a too nice feature.

TIA, Uli

it is the method name

@Override
public Class<? extends ITemplateProposalProvider> bindITemplateProposalProvider() {
return MyDslTemplateProposalProvider.class;
}

sorry, I found the typo:
should read bindITemplateProposalProvider()

Hi Dietrich, thank you very much for the fast reply.

So the good news:

we can still (2.8 at least) use dynamic templates with xtext DSL in the ContentAssist.
(I asked on xtextcon 2015, if this is possible, but noone pointed me to that solution).

does it work with

@Override
public Class<? extends ITemplateProposalProvider> bindITemplateProposalProvider() {
return MyDslTemplateProposalProvider.class;
}

??
