Hello QVTO-World,
I'm sure, I got something wrong with UML tagged values. I defined a stereotype "A" with tags
"aint : Integer [1]",
"astr : String[1]",
"astrarr : String[*]".
With applying A to a class, I tagged the values with aint = 1,
astr = "Hello",
astrarr = "Hello", "World, "how", "are", "you".
Now I want to analyse that class with QVTO:
query Class::checkStereotype(str : String) : Boolean
{
log ('checkStereotype:');
var st := self.getAppliedStereotype( str );
log ( ' stereotype ' + st.name );
var tvint := self.getValue ( st, 'aint' );
log ( ' tvint as it is ', tvint );
-- this is OK
var tvstr := self.getValue ( st, 'astr' );
log ( ' tvstr as it is ', tvstr );
log ( ' tvstr as String ' + tvstr.oclAsType(String));
self.setValue ( st, 'astr', 'HelloWorld' );
tvstr := self.getValue ( st, 'astr' );
log ( ' tvstr as String ' + tvstr.oclAsType(String));
-- this is OK
var tvstrarr := self.getValue ( st, 'astrarr' );
log ( ' tvstrarr as it is ', tvstrarr );
printTaggedValues(tvstrarr.oclAsType(Sequence(String)));
/*
this is not; the log delivers "Hello"; I expect something like "Hello", "World", ...
The function call printTaggedValeus results with "invalid value"
*/
return true;
}
Any help? Thanks for it,
Siegfried

Hi Siegfried,
When trying to reproduce, I saw that getValue(...)
for a String[*] type value gives an empty list which is converted
due to a strange repeated value coercion in OCL into invalid.
Could you please raise a bugzilla and attach your models and
relevant QVT code please?

Also, I'm just curious if you get a correct value when you access it in
Java,
I wonder whether I had a correct setup for this scenario.

Hi,
I was wondering if there was any progress on this issue. Are there other
ways to get the values of a multivalued tagged value?
Dear regards,
Tony.
