Clojure / seeseaw.core / table lazy-seq检索失败

Question

我的“（list-projects）”方法从SQLITE数据库中查询出一个映射。

    (doall (apply prn (pm.models.db/list-projects)))    

pm.core==>{:id 1, :name "MyTestProj", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 2, :name "newproject1", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 3, :name "newproject1", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 4, :name "abc", :owner "def", :date "2017-12-19 13:12:45"} {:id 5, :name "abc", :owner "def", :date "2017-12-19 13:12:45"} {:id 6, :name "abc", :owner "def", :date "2017-12-19 13:12:45"} {:id 7, :name "newproject1", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 8, :name "", :owner "", :date strong text"2017-12-19 13:12:45"}

在构造seesaw.core / frame / mig-panel / table（JFrame / JPanel / JTable）时，我想使用：row属性填充一个seesaw.core / table（Java JTable）和那些结果。

(def main-panel 
  (mig-panel
  :constraints ["fill, ins 0"]
  :items [[(seesaw.core/table
                  :id :tbl1
                  :size [640 :by 480]
                  :model [:columns [:id :name :owner :date]
                          :rows [(doall (apply prn (pm.models.db/list-projects)))]
                         ]) "grow"]
         ]))

2. Unhandled clojure.lang.Compiler$CompilerException
   Error compiling form-init4108264894568019320.clj at (44:16)
   ang.Thread/run

1. Caused by java.lang.IllegalArgumentException
   row must be a map or vector, got null

如果我插入地图{：id 1，：name“MyTestProj”，：owner“mbc”，：date“2017-12-19 13:12:45”} {：id ........} { } {} {} {}直接，它工作正常，表中的行被正确填充，因此（doall（应用prn（pm.models.db / list-projects）））的输出格式是我需要的。

如何在seesaw.core / mig-panel的上下文中检索（我推测）lazy-seq？谢谢莫蒂默

Answer 1

pm.core> (pm.models.db/list-projects)
({:id 1, :name "MyTestProj", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 2, :name "newproject1", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 3, :name "newproject1", :owner "mbc", :date "2017-12-19 13:12:45"} {:id 4, :name "abc", :owner "def", :date "2017-12-19 13:12:45"} {:id 5, :name "abc", :owner "def", :date "2017-12-19 13:12:45"} )
pm.core> 

（pm.models.db / list-projects）产生一个列表，该列表可以直接用作：rows键（无括号）的值。 ：rows（pm.models.db / list-projects）

感谢Carcigenicate的建议。
