Can anybody tell me in what circumstances, we use data loop connectors in MQWF
Buildtime?
I have a situaion, where I am using a block activity. I am sending
the value of one of the paratmeters "required count" as 3 & "current count" = 0.
The block's exit condition is "current count >= required count".
Can anybody tell me how do I increment the current count in build time, so that the
block will execute multiple times until it met the exit condition.
I would appreciate if anybody can explain me in detail.
Thanks
Mike. |

I don't think you can do that. You will have to write your own utility to do the incrementing. |

Thats right. You cannot acheive it in buildtime.
The usage of data connectors :
For example in the scenario you have described you can use data loop connectors , to send the output container values back to the input containers. Say the variable 'current count' value is 1 after first iteration.
And you need to save this value for the second iteration, so send it back to the input container using data loop connector.
But the actual increment of the variable 'current count' needs to be done outside of Buildtime.
Hope this helps.

In one of your activities inside the block you would access the value of the counter from the input container increment it, then set it into the output container. It doesn't have to be a "utility" as Venny is saying, its just that someplace inside the block one of the activities needs to increment this counter, and map it back to the sink.
