Cannot invoke method getId() on null object

[Jonathan Share]

Hi,

I've just had the latest updates that happened over easter come in,
I've updated my pom's to add the new dependency and update selenium to
1.0.1-te3-SNAPSHOT however my tests are failing on the following, very
simple definition.

ui.Container(uid: "header", locator: "//table[@class =
'outerBox']/tbody/tr[1]") {
Container(uid: "nav", clocator: [tag: "table"]) {
UrlLink(uid: "logout", clocator: [href: "*logout.do"])
}
}

As I've used xpath here I tried adding a call to disableCssSelector()
however this has no effect. Stacktrace is below.

Do I really have to go through and change out all of my XPaths? Or is
there another configuration directive I should try?

Regards,

Jonathan

After commenting out this definition and updating all tables and lists
to the new UID format my test is now able to start running (although I
have other problems) so this issue doesn't seem to be xpath related.

[Jonathan Share]

After renaming the outer container to head instead of header, my code
now works again.

Yes, the UI template should be included in "{ }" now, otherwise, the parser
cannot differentiate the id from the template index.

Do you mean that you cannot use "header" as the uid? Strange. I will take a look.

Thanks,

Jian

Yes, that's what I meant, this wasn't in a template

[Jian Fang]

I can see why now. ANTLR 3 defined a implicit token  'header' when it saw the grammar such as

'{' 'header' ':' INDEX '}' 'as' ID

Since the "header" is reserved as a token, ANTLR 3 tried to match the grammar 'header' : index. Similarly,
the "->" is also an implicit token, when ANTLR 3 saw "-", it tried to match it with "->".

As a result, the implicit tokens such as "header", "footer", "row", "column", and "tbody"
are all reserved for UDL and they cannot be used as IDs.

But UDL is case-sensitive, you can still use "Header", "Footer", "Row", "Column", and "TBody" as IDs.

Thanks,

Jian
