Ryan Vanderwerf commented on GROOVY-9069: ----------------------------------------- ok I'll make a standalone example soon that replicats this and put it here. > 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 > Priority: Major > > 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. > {code:java} > 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 > } > } > {code} > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
