How to initiate validation of a SSE StructuredDocument [message #208354]

I have a quick fix proposal that will fix an EL problem by creating a
variable outside of the current source viewer. This means that the
proposal won't update the current text region to become dirty, and
therefore won't re-validate automatically.

Ideally I would like to validate only the current region, but in some
cases I may want to re-validate the entire document. I want to do this
when the proposal is applied.

Is there API to initiate validation of a SSE StructuredDocument or a
region within?

Regards,
Gerry

Gerry,
You'll want to look up the org.eclipse.wst.sse.ui.sourcevalidation
extension point and the
org.eclipse.wst.sse.ui.internal.reconcile.validator.ISourceV alidator
interface (which will at least be moved into sse.core at some point).

Nitin,
Maybe I wasn't quite clear, or maybe I am missing something. We already
have a source validator. During validation, we are attaching an
IQuickFixProcessor using message.setAttribute in the prescribed manner of
https://bugs.eclipse.org/bugs/show_bug.cgi?id=170988.

The issue here is that the source will not change after applying this
particular proposal, so a validation will not re-fire automatically. How
can I cause a re-validation event?

There's no direct way of causing this, much less a supported one. I
suppose the only thing you could do as a workaround is to replace
the text spanning the annotation's offset and length with the same
text, forcing the document event to be generated and the area to be
revalidated.

What about using this new validation framework object?

Validator[] validators = ValidationFramework.getValidatorsFor(...).

for (Validator validator : validators)
{
validator.validate(...);
}

--Cam

There's a catch in that the output from those validators would need
to be rerouted to create text Annotations (they make the squiggles),
something that's only done by the editor's internals.
