The main principle is: when struts1.* is displayed in jsp, the property value will be first taken out from the formbean through the get*** method! !
flowFormFieldCfgElement(#itemIndex#).name This is the core. If flowFormFieldCfgElement(#itemIndex#) is empty, an error will occur, so in /** form complex properties */
public FlowformFieldConfig getFlowFormFieldCfgElement(String key){
if(!(key)){
(key, new FlowformFieldConfig());
}
return (key);
}
Make a judgment! !
