[Xpand] Root element not found [message #643365]

Hi,

I have a question according to Xpand and I guess this is the right location for that, next to Xtext?!

I have a grammar with top-level element "WebsiteModel":
...
WebsiteModel:
'site' title=STRING
pages+=WebPage+
...

When I try to generate code out of an instanz of my grammar with a workflow configuration as follows (excerpt)...:
load = {
slot = "websiteRoot"
type = "WebsiteModel"
}

...the console output is telling me, that no element of that type has been found. However, when I use a non-top-level element (e.g. WebPage) in the workflow configuration, the result set is not empty as expected.

Is there a certain trick I missed to access the root element in order to perform Xpand transformations?

Thnx,
Stefan

PS: Well, this question seems to be better off in the M2T forum. @Admin: Don't mind to delete this post. I put a duplicate in the M2T forum.

Hi,

the reader only "exports" Elements that have a QualifiedName to the Xpand generator component. so use a IQualifiedNameProvider tp give your WebsiteModel a name.

Hi Christian,

thnx for the hint!

According to that I played around a bit and found that changing WebsiteModel's "title=STRING" to "name=STRING" in my grammar is qualified enough for the reader Wink

...
WebsiteModel:
'site' name=STRING
pages+=WebPage+
...

Thanks a lot! This problem nearly drove me mad.

Stefan
