How to remove existing values from the input fields?

Hi,

I'm trying to automate my page which contains certain input fields like textbox, drop down, button etc.

I have defined three methods for the following functionalities:

1. Open application
2. Get data from excel
3. Save data
4. Clear input fields after saved

Its working fine for the first iteration. Next time, the input field information are not cleared even I have used the script as below.

driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.findElement(By.id("j_idt51:serviceLocationID")).clear();

driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.findElement(By.id("j_idt51:AssigningAuthoritySystemVendorCode")).clear();

Note: Its appending new cell information with the existing information in the input fields.

Please help me to solve this problem.

Thanks

Is the page being submitted when you save the data or is it an ajax call.
If the page is being submitted, then the elements driver reference to the elements will no longer be the same.

try to print or debug the values
driver.findElement(By.id("j_idt51:serviceLocationID"))
driver.findElement(By.id("j_idt51:AssigningAuthoritySystemVendorCode"))

check whether they are null, also please post the error stack.
