I have a JComboBox named "jComboBox18" and a JTextArea "jTextArea11". Now I want that whenever a item is selected from the "jComboBox18" combo box its corresponding description is shown in the "jTextArea11" textarea.
I have added the appropriate listener to the JComboBox But the JTextArea is not showing any text. The code that I have written is as follows:
private void jComboBox18ItemStateChanged(java.awt.event.ItemEvent evt) {
Object item = jComboBox18.getSelectedItem();
if(item != null) {
ems.logic.Process selectedProcess = (ems.logic.Process)item;
jTextArea11.setText(selectedProcess.getProcessDescription());
jTextArea11.updateUI();
jTextArea11.revalidate();
jTextArea11.validate();
}
}
=====================EDITED===========================================
The method is being called for sure. I am changing the state of one more combobox
which is also being written in this method and its state changes successfully whenever item is selected from the "jComboBox18"
