How to override context variable?

[Anonymous]

Hi,

I want to change the value of a context variable and save it permanently in a context file.

Here is what I tried already : 

The System.out.println() gives me a "b", but when I go into the file written by the tContextDump component it still prints an "a" :

Thanks for the help.

Hi,

You need to use tContextLoad to update your context, so you need to follow this design:

As you see the context contains 3 variables. tLogRow_45 gives the initial values for them.

In tJavaRow, I set the value of the "sample" variable like this before to use tContextLoad:

output_row.key = input_row.key;
if(input_row.key.equals("sample"))
  output_row.value = "100";
else
  output_row.value = input_row.value;

Then the next tContextDump gives me the expected result as you can see.

That's for the principle, maybe there is other approach to do that.
