#15726 new enhancement

Not returning the value when using tag()

Reported by: naoliv Owned by: team
Priority: normal Milestone:
Component: Core validator Version:
Keywords: mapcss Cc:


Have this small validation rule:

*[foo = bar] {
        throwWarning: tr("something {0}={1}", "{0.key}", tag("{0.key}"));

and validate an object with foo=bar
We can see a message saying something foo=null

Of course the common usage is {0.value} instead tag("{0.key}"), but since tag(key_name) description says "get the value of the key key_name from the object in question", shouldn't we see the same result regardless which one we choose here?

As a real example (and for context), I was trying to test some rules for #15719:

*[distance =~ /^[0-9]+,[0-9]+$/],
*[ele =~ /^[0-9]+,[0-9]+$/],
*[height =~ /^[0-9]+,[0-9]+$/],
*[width =~ /^[0-9]+,[0-9]+$/] {
        throwWarning: tr("some message for the comma");
        fixAdd: concat("{0.key}=", replace(tag("{0.key}"), ",", "."));

But it deletes the key (since the value is null)

Type: defectenhancement

more like an enhancement than a defect, see ticket:15719#comment:4

for now it works with examples similar to ticket:15719#comment:2 or r12215 or r13345
