Description
In order to get the GORM codebase to compile I had to make this change:
https://github.com/grails/grails-data-mapping/commit/1ef850c496d13d8ca915b27e76b6bfdb4e27377e
The code in question is:
/**
* Sets multipart values within the request body
*
* @param name The name of the multipart
* @param value The value of the multipart
*/
void setProperty(String name, value) {
if (value instanceof File) {
value = new FileSystemResource(value)
}
else if (value instanceof URL) {
value = new UrlResource(value)
}
else if (value instanceof InputStream) {
value = new InputStreamResource(value)
}
else if (value instanceof GString) {
value = value.toString()
}
if( mvm[name] ) {
mvm[name].add value
}
else {
mvm.put(name, [value]) // <--- FAILS COMPILATION HERE
}
}
No matter what I tried I could not get it into to compile. The method accepts `put(String, List<Object>)` but fails compilation with:
RequestCustomizer.groovy: 392: [Static type checking] - Cannot call org.springframework.util.MultiValueMap <String, Object>#put(java.lang.String, java.lang.Object) with arguments [java.lang.String, java.util.List <java.lang.String>] @ line 392, column 13. mvm.put(name, [value]) ^
Altering the code to:
List<Object> values = [value]
mvm.put(name, values)
Fails with:
RequestCustomizer.groovy: 392: [Static type checking] - Incompatible generic argument types. Cannot assign java.util.List <java.lang.String> to: java.util.List <Object> @ line 392, column 35. List<Object> values = [value] ^ RequestCustomizer.groovy: 393: [Static type checking] - Cannot call org.springframework.util.MultiValueMap <String, Object>#put(java.lang.String, java.lang.Object) with arguments [java.lang.String, java.util.List <java.lang.String>] @ line 393, column 13. mvm.put(name, values) ^ 2 errors
