Hello,
I have to transform an Attribute of type Integer to and attribute on type Long.
If I simply do
precision <- s.precision
where s.precesion is of type Integer and precision is or f type Long.
I have the following error message:
org.eclipse.m2m.atl.engine.vm.VMException: Cannot set feature OUTMODEL!MetadataColumn.precision to value 10
at A.__applyMetadataColumn(1 : NTransientLink;) : ??#96(TosMetadata400to410.atl[66:9-66:33])
local variables = {t=OUT!<notnamedyet>, s=IN!<unnamed>, link=TransientLink {rule = 'MetadataColumn', sourceElements = {s = IN!<unnamed>}, targetElements = {t = OUT!<notnamedyet>, newInitialValue = OUT!<unnamed>}, variables = {}}, self=TosMetadata400to410 : ASMModule, newInitialValue=OUT!<unnamed>}
local stack = [OUT!<notnamedyet>]
Java Stack:
