Třída OpenComponentAction je docela krátká:
54 final class OpenComponentAction implements ActionListener {
55 private TopComponent component;
56 private final Map<?,?> map;
57
58 OpenComponentAction(TopComponent component) {
59 assert component != null; //to diagnose #185355
60 this.component = component;
61 map = null;
62 }
63
64 OpenComponentAction(Map<?,?> map) {
65 this.map = map;
66 }
67
68 private TopComponent getTopComponent() {
69 assert EventQueue.isDispatchThread();
70 if (component != null) {
71 return component;
72 }
73 TopComponent c = null;
74 Object id = map.get("preferredID"); // NOI18N
75 if (id instanceof String) {
76 c =
WindowManager.getDefault().findTopComponent((String)id);
77 }
78 if (c == null) {
79 c = (TopComponent)map.get("component");
80 }
81 if (id != null) {
82 component = c;
83 }
84 return c;
85 }
86
87 public void actionPerformed(ActionEvent e) {
88 TopComponent win = getTopComponent();
89 win.open();
90 win.requestActive();
91 }
92 }
Jinak ten stack trace je kompletní. Zkontroloval bych konfigurační soubory
platformy NetBeans.
