No initial ValidationJob [message #670285]

Hi

When an Xtext editor starts, there is no invocation of the
ValidationJob, so the editor displays whatever historical problem
markers may exist. These may be very wrong. After a dummy edit the
ValidationJob runs and all is sensible.

I recall a Bugzilla response a while ago, when I understood less about
Xtext, that this was intended behaviour and matched JDT.

I don't think it does. Is it really correct for the initial editor
display to be so wrong?

(I do not have the Xtext nature and so builder active.)

Regards

Ed Willink

Hi Ed,

you can bind the ValidatingEditorCallback for your language. It is meant
to be used for languages that do not use the builder infrastructure. In
any other case, the markers should be in sync with the file's content as
long as you do not change your validation rules. That's why we do not
trigger an initial validation by default.

Regards,
Sebastian

Hi Sebastian

Thanks; works beautifully.

[For anyone else reading: bind ValidatingEditorCallback as
IXtextEditorCallback.]

Regards

Ed
