Hi,

My code is like this:

if (row.abc1== ‘pnc’)

```
  action1

```

end

if (abc2 == ‘hjayu’)

```
   action2

```

end

Now the probelm is, before finishing the action1, it is going to perform  
action2 & resulting crashing the system.

what might be the problem, can somebody pls help

Thanks in advance

Does action1 run on a different thread than the one the method was  
called? Like:

def action1  
Thread.new do  
#your code here  
end  
end

Be wary that it might be that what happens inside action1 runs on a  
different thread, just not explicitly like this, for example it might  
call a library that runs its stuff on a separate thread. Could you show  
more of what happens inside action1() ?

Thanks for ur reply Andrea,

It is like this,

if (abc1 = fgd)  
click link1  
enter value1  
enter value2  
click ok  
end  
if (abc2 = fge)  
click link2  
select a check box1  
enter value1  
click ok  
end

Thanks

Hei,

> click ok

Still, i don’t understand what’s going on 🙂  
One quick and dirty (REALLY dirty) fix might be to check, before the  
abc2 == (mind the ==, NOT = ) fge condition evaluation, if the system is  
in a suitable state for the operation to be run and, if not, wait a  
little until it’s ready. Something like:

if (abc1 == fgd)  
click link1  
enter value1  
enter value2  
click ok  
end

while !operation\_over?  
sleep(1)  
end

if (abc2 = fge)  
click link2  
select a check box1  
enter value1  
click ok  
end

where operation\_over? is a method that you will have to write that  
checks for the system to be in a proper state: it should return true if  
the operation run after the first condition is over, false otherwise.  
But really, think twice before doing this: the problem you’re  
experiencing derives from some global value you’re changing, and  
global’s bad 🙂 i suggest you check for what’s going on deep under and  
fix the underlying problem instead of writing this hack.
