---------------------------------------
Summary: assignment in map by named index causes casting error
Key: GROOVY-9069
URL: https://issues.apache.org/jira/browse/GROOVY-9069
Project: Groovy
Issue Type: Bug
Components: groovy-runtime
Affects Versions: 2.5.6
Environment: Linux Mint 19.1
Reporter: Ryan Vanderwerf
If I assign a value to a collection via a named index (key name) I get a
casting error like so:
Failed to convert property value of type 'java.util.LinkedHashMap' to required
type 'java.util.Map' for property 'methodConfigNames'
Here is the code in question. This doesn't happen in Groovy 2.4.15. Because
Grails 4 is running 2.5.6, many plugins are failing with this error.
void setMethodConfigNames(Map<String, Map<String, List<String>>>
methodConfigNames) {
methodConfigNames.each { String key, Map<String, List<String>> value ->
Map<String, List<ConfigAttribute>> configs = [:]
populateMap configs, value
methodConfigs[key] = configs // fails
//methodConfigs.put(key,configs) // works
}
}
If this could get resolved it would save a lot of plugins from having to be
re-released with the workaround making less confusion about the error. In some
cases this works and some it doesn't. Even though I have @CompileStatic set,
the issue happens at runtime.
