Event handling while changing the value or clicking the button

Question

Hi All,
I am working on Jdeveloper 11.1.1.5.
I have a must requirement where i have a textbox and a button.
Now if a user changes the value of the textbox then i need to show a dialog to the user for the confirmation that whether he wants to continue or not.
And on click of button i execute my business logic and commit in the database.
NOTE :- I am opening that dialog on the valueChangeEvent of the textbox.
Case 1 :-
User enter a value in the textbox and tab out the field , value change occurs and dialog displayed onto the page. -> CORRECT
Case 2 :-
User enter a value in the textbox and does not tab out the field and directly click on the button.In that case , actually valueChange and button code both executes at the same time.I mean to say , the user click on the button , i get the dialog , but my business logic also gets executed. -> INCORRECT(ISSUE)
How should i restrict the button logic to be executed till the dialog has been shown and user has confirmed.
Kindly suggest!!!

Shah

Hi Shah,
You can try something like this:
<af:inputText autoSubmit="true" id="it1" ...>
  <af:setPropertyListener from="true" to="#{viewScope.uncommittedData}" type="valueChange"/>
</af:inputText>
<af:commandButton partialTriggers="it1" disabled="#{viewScope.uncommittedData ne 'true'}" .../>AP
