Coldfusion - runAsnyc 方法不允许实例化 Bean
Coldfusion - runAsnyc method not allowing the instantiation of Beans
问:
我的基本示例错误与空点异常错误。此错误仅在我们实例化基本 Bean 时才会显现。在 Async 中实例化 bean 是否有某种限制?
Coldfusion 2018 - V 2018.0.08.330106
Bean 代码
<cfcomponent displayname="TestBean" hint="I model a single TestBean." output="false">
<!--- CONSTRUCTOR --->
<cffunction name="init" access="public" output="false" returntype="TestBean">
<cfscript>
return(this);
</cfscript>
</cffunction>
</cfcomponent>
测试 CFM 代码
<cfscript>
arErrors= [];
initiatedAsyncProcesses = [];
initiatedAsyncProcesses.append(runAsync(function() {
local.TestBean = new TestBean();
}).error(
function(error){arrayAppend(arErrors, error)}
));
//Wait for errors
sleep(100);
writedump(arErrors);
</cfscript>
Complete
产生错误
