How to Handle Modal dialog window issue (Using Selenium IDE) in Firefox 3.0

Hi,

I have an issue regarding the modal dailog window using IDE in firefox browser.

Problem: In one of my application, after i click on Add button (selenium.click("ctl00_ContentPlaceHolderRight_btnAddContract").A modal dialog window is displayed.In that modal window, i want to enter certain input data(Refer the code 2),but here the focus is not moved to that modal window from the parent window.I thought after modal window appeared the javascript gets suspended for the parent.Selenium still pointing to the parent window also gets suspended.Finally the rest of the code gets suspended.


Here i use Selenium RC.


Code 1:
Line 1:selenium.click("ctl00_ContentPlaceHolderRight_btnAddContract");
Line 2:selenium.waitForPageToLoad("120000");


Code 2:
Modal Window Fields:
Line 3: selenium.type("ctl00_ContentPlaceHolderRight_txtContractName,"Contract_Name2")

Line 4 :selenium.type("ctl00_ContentPlaceHolderRight_txtSystemRec",Contract_SystemRec")

Line 5: selenium.type(]"ctl00_ContentPlaceHolderRight_txtSystemRecordID", Contract_SystemRecordID");

Contract_Name2,Contract_SystemRec,Contract_SystemRecordID - These are all parameterized Input(From Excel Doc).


Can any one please provide me a solution for this issue ?
