It may help.   Best regards Michal Fri, 05 Apr 2019 11:37:00 GMT MichalSzumski 2019-04-05T11:37:00Z https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56679#M10820  I have constructed a 'Basic Actions' Object and 'Business Use' object both for a Web Application. 1) The Attach stage works well for the Basic Actions object. However for the Business Use object it works on teh SECOND iteration. From an understanding perspective, I would like to know why this is the case ?   Reference:   Basic Actions Object - has actions Launch, Login, Logout and Attach etc.   Business Use Object - has actions Attach, DoBusiness... etc. Thu, 04 Apr 2019 18:39:00 GMT https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56679#M10820 SaurabhPalkar 2019-04-04T18:39:00Z https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56680#M10821 Hi, spalkar, it is hard to tell based on information provided. How did you discovered it works for the second iteration? Desribe in more detail the sequence - when you launch, then you immediately call Do Business or how it works?

This is the Attach page. The first time 'Attach' stage is called it fails. I try it a second time and then it works.  ( So my question is why does this happen)   Thu, 04 Apr 2019 20:25:00 GMT https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56681#M10822 SaurabhPalkar 2019-04-04T20:25:00Z https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56682#M10823 Hi spalkar,   Could You collect error info and provide?

When running through control room, 'Attach' action could called way too early. Have you tried in debug more if it works without retrying?  Tue, 09 Apr 2019 02:19:00 GMT https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56684#M10825 pranavred 2019-04-09T02:19:00Z https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56685#M10826 Well, hard to tell even after the information you provided. I assume that you call a process, from a process you call Basic Actions Object and Launch, right? Then you call Business Use Object attach. And after this sequence of steps you are saying that attach works only during second attempt. Am I right? If this is the scenario then I do not have any explanation because it should work fine. May be if you can show us the log file that could shed some light on the issue you are facing.

So I have moved forward now by just re-trying the attach a second time.     Fri, 12 Apr 2019 01:18:00 GMT https://community.blueprism.com/t5/Product-Forum/ATTACH-works-on-the-Second-iteration-and-not-the-first-why/m-p/56686#M10827 SaurabhPalkar 2019-04-12T01:18:00Z
