Hi, I made a few minor modifications to a erstwhile working applet and get the following error message : ... cannot resolve symbol symbol : variable search location : class java.awt.Panel PanelCliInfo.search.ActionListener(this); ... The complete applet is big, so here is the gist of it :
this is an innerclass problom .. change PanelCliInfo.search.addActionListener(this); // this DOES NOT WORK! to demoApplet.this.PanelCliInfo.search.addActionListener(this); this will work basha

Hi. Thanks for that, it compiles fine again.
However, when I try to run it after modifying and recompiling, I get this unusual runtime error on the java console :
When I re-instate the original applet without the inner panel p2, it works fine again and does not throw the NullPointer Exception ! The error message is too cryptic for me to begin debugging it. Nice Chrissy treat from JAVA. Can you please explain the theory behind the "inner class" to me ? It would be nice to understand wy it compiles.
THX Merry Christmas .
