Hi,

In the standalone version, we can easily have access to the ProposalProvider and, thus, to get access to user defined proposal templates. How this proposal provider can be accessed by a Xtext Web application? Do we need to programmatically define the access to the proposal prodicer already given for the standalone version?

Best Regards

hi,

can you be a bit more specific about your question.
the web version has support for proposals by default. (crtl + space)

the proposal provider to implement (subclass) and bind (in the webmodule) is

class MyDslWebModule extends AbstractMyDslWebModule {
	def Class<? extends IdeContentProposalProvider> bindIdeContentProposalProvider() {
		MyDslProposalProvider
	}
}

class MyDslProposalProvider extends IdeContentProposalProvider {
	
	override createProposals(Collection<ContentAssistContext> contexts, IIdeContentProposalAcceptor acceptor) {
		println("start here")
		super.createProposals(contexts, acceptor)
	}
	
}

In the ProposalProvider.xtend, i have inserted code for completing my 'code' when the Ctrl+space is pressed.
However, this is not accessed by the Web application as in the standalone.
I inserted the code you mention but my ProposalProvider is not seen by the WebModule
e.g., i get an error when inserting the code in the WebModule.xtend
def Class<? extends IdeContentProposalProvider> bindIdeContentProposalProvider() {
XProposalProvider <--- error: The method or field XProposalProvider is undefined
}

Are you sure you did the class path right. In doubt place the class right
next to the wrbmodule. It might be you need to write a least one char to
get a initial server sync.

Btw what do you mean by standalone

I mean that when i run my dsl as an Eclipse plugin, the proposal provider is ok.
In the Web module, the Ctrl+space presents the list of the proposals but when pressing the enter,
the template i inserted in the XProposalProvider.xtend is not placed in the editor.
Btw, in my Eclipse, the XProposalProvider.xtend is in the ui project and not in the ide.
