ZK 8.0.3 S3
Reproduce with:
my.app.label.a= Label A
my.app.label.a.b= ${my.app.label.a.$}
my.app.label.a.b.c= ${my.app.label.a.b}
<zk> <div> <vlayout> <label value="${labels.my.app.label.a.$}"/> <label value="${labels.my.app.label.a.b}"/> <label value="${labels.my.app.label.a.b.c}"/> </vlayout> </div> </zk>
In ZK 8.0.1 in zk-label.properties if a label targets its own parent value for its value, the value would be a string representation of the label map.
such as:
In ZK 8.0.2
If the label is a member of the parent target, the following exception is throw when the result is a loop.
