The problem is to avoid the duplicate text of 1st jformattedtextfield to be entered in 2nd jformattedtextfield. i need to display meesage if two textfields has same text.

I am able to provide the message only when focus lost event takes places. I want to display the message as soon the duplicate text is entered in jformattedtextfield. Please help me to proceed.


Thanks in advance,

Use a DocumentListener.

I would use a DocumentFilter for this.

Thanks. I have used DocumentFilter and it works.

Now my scenario is when i do data validation, navigation to other screens should not be allowed unless valid input is entered in these textfields.

My window has Jtabbedpane which has 3 tabs. Above mentioned Jformattedtextfields is available in one of the tabs. If these textfields has: Duplicate value, empty or invalid data, validation is done and message is displayed.

If one of the text field has duplicate value/empty/invalid data and cursor is still available in the textfield and one of the tab panel is selected, then the validation message is displayed on that tabbed panel.

I need to restrict navigation and display this validation message on the panel where these textfields are available.

Please help me to resolve this issue.


Don't get me started about those stupid light bulbs.
