This i red also on the styles rules-page in OSMWiki and e.g.
highway=* {name '${ref|highway-symbol:oval:6:4} ${name}' |
'${ref|highway-symbol:oval}' | '${name}'}
highway=* {name '${ref|highway-symbol:box:6:4} ${name}' |
'${ref|highway-symbol:box}' | '${name}' }
results as expected in a label with oval highway shield and the second
rule is ignored.
But with
highway=* & maxheight>0 {set nameheight='H=${maxheight}'}
highway=* & maxheight>0 {name
'${nameheight|highway-symbol:box:6:4} ${name}' |
'${ref|highway-symbol:box}' | '${name}'}
both actions will be applied althought it's the same rule. According to
your explanation only the temporary tag should be set but the second
line not be taken.
I have put both actions in to one rule :
highway=* & maxheight>0 {set nameheight='H=${maxheight}' ; name
'${nameheight|highway-symbol:box:6:4} ${name}' |
'${ref|highway-symbol:box}' | '${name}' }
This gives me the same result as with the two lines above.
May be it's simply an accident caused by ??? or couldn't it be that in
some circumstances, the analysis of the rules will be handled different.
