在UI中，基于列表中的项目数，被调用的模板不止一次呈现。如果“complatedTaskList”模板中有两个项目，则同样会呈现两次。
答案 0 :(得分：3)
因为您正在将一个集合传递到g:render
<g:render template="/templates/completedTasksTemplate"
var="completedTask" collection="${completedTaskList}" />
根据docs
对于List，将为每个实例重复模板
如果您只希望将一个项目传递到列表中，那么您可以这样做
<g:render template="/templates/completedTasksTemplate"
var="completedTask" collection="${completedTaskList[0]}" />
