Janak That was precisely the problem The db request was performed by other thread. I removed the thread and everything works fine.
Thank you very much Agustín T. Ramos Fonseca "Janak Mulani" <[EMAIL PROTECTED]> 23/05/2006 09:52 a.m. Please respond to "[EMAIL PROTECTED] Com" <[EMAIL PROTECTED]> To <[EMAIL PROTECTED]> cc <[email protected]> Subject RE: [ULC-developer] Problem updating the ui Hi, Could you please send me the snippet from QueryPoliciesPane where you are setting text on ULCTextField? It seems to me you are trying to setValue on a ULC widget from a separate thread. In a ULC application you are not allowed to spawn separate thread and neither should you access ULC widgets from that thread.

My app just receives some parameters and executes a query, and it;'s supposed to update a table and a textfield. The problem is when trying to update the table (or for that matter, whatever ui component). Using tomcat, I get the following in stdout.log java.lang.NullPointerException at com.ulcjava.base.application.ULCProxy.a(ULCProxy.java:13) at com.ulcjava.base.application.ULCProxy.a(ULCProxy.java:245) at com.ulcjava.base.application.ULCProxy.a(ULCProxy.java:430) at com.ulcjava.base.application.ULCProxy.a(ULCProxy.java:121) at com.ulcjava.base.application.ULCProxy.setStateUI(ULCProxy.java:256) at com.ulcjava.base.application.ULCTextComponent.setValue(ULCTextComponent.java :30) at com.ulcjava.base.application.ULCTextField.setValue(ULCTextField.java:1) at com.ulcjava.base.application.ULCTextComponent.setText(ULCTextComponent.java: 51) at com.ulcjava.base.application.ULCTextField.setText(ULCTextField.java:22) at com.ulcjava.sample.onlineshop.view.QueryPoliciesPane$1$1.run(QueryPoliciesPa ne.java:122) Here is another version of the same stuff. java.lang.NullPointerException at com.ulcjava.base.application.ULCProxy.a(ULCProxy.java:231) at com.ulcjava.base.application.ULCProxy.invokeUI(ULCProxy.java:276) at com.ulcjava.base.application.ULCProxy.invokeUI(ULCProxy.java:72) at com.ulcjava.base.application.ULCComponent.repaint(ULCComponent.java:232) at com.ulcjava.sample.onlineshop.view.QueryPoliciesPane$1$1.run(QueryPoliciesPa ne.java:117) Please, Does anyoune know what could be wrong?
