How to change value of table field?? Please guide...

Vaadin 6 / 7 / 8 Framework UI

Hi,

I am new to vaadin.
Can anyone please explain, how to change the value of a table field in vaadin.
I have to display different status in one table field.

I tried using something like,

Function name()
{
table.field.setvalue(“Executing”);

// Code for execution

if(processed)
{
table.field.setvalue(“Execution complete”);
}
else
{
table.field.setvalue(“Execution failed”);
}

I am never able to see the status EXECUTING on the screen. It directly shows “Execution complete” or “Execution failed”

Please guide. I have strict client deadlines to follow.

As long as your execution is not done in an extra-thread, this cannot work as your method will be executed as a whole before its results are getting displayed to the client. And this causes the set value of “Executing” always being overridden by either “Execution completed” or “Execution failed”.
