This part source code have been realized by another company and it can't be modify. It works properly and this is my problem - how prepare testing in this environment for modifying part application only. You see, it's politically complicated. 🙂 For explanation - in HTML code all the parent object declarations (like below) are permanently exists. <parent1 class = class1 class2 class3 name=... > <parent1 class = class1 class2 name=... > ... <parent1 class = class1 class2 class3 name=... > The name of class3 is "ng-hide" - it may help more explains this specific situation. But I hope, I found resolving but please, be patient. I want to indicate my previous insight: I may change unrecognized status manually by unmark and then mark again mapped declaration. After then, it can (proper) recognize parent mapped object by "Highlight" menu order (and of course child too). At the beginning, I have prepared other Keyword Test with loop and called a main Keyword Test (without loop). I have hoped - maybe each new calls Keyword Test could find the proper path to object by saved mapping (with pseudo-class): .class11.class12:not(.class13) > .class21 Unlikely, without success. And then, I found method RefreshMappingInfo. Now, it still works properly. It's amazing. Of course, before call child object (in the loop) I call RefreshMappingInfo method on parent object. I hope, it will be stable resolving. If not, I come back here. Really thanks for all of you. Re: loosing mapped web object Is Regular Expressions and Wildcards only option in that situation ? Is it the proper/expected behavior of Test Complete ? loosing mapped web object Hi, The parent web object in Name Mapping has prepared declaration: .class11.class12:not(.class13) > .class21 Similar example css setting there are at first picture here => https://support.smartbear.com/testcomplete/docs/testing-with/object-identification/name-mapping/selectors.html . My Keyword Test uses this mapped object in a loop. It works during first run properly but in the second turn I getting error of unrecognized child object (because above described parent is unrecognized) with the log message below: The window size is (0, 0); the screen rectangle: the left top corner is (0, 99), the right bottom corner is (0, 99). I may change unrecognized status manually by unmark and then mark again mapped declaration. After then, it can recognize parent mapped object by "Highlight" menu order (and of course child too). What I may do for improve this situation ? For explanation - HTML code I work for has parent object declaration lines like below: <parent1 class = class1 class2 class3 name=... > <parent1 class = class1 class2 name=... > ... <parent1 class = class1 class2 class3 name=... > I must indicate this one parent object which has no class3. Test Complete is mapping this object as .class1:nth-child(<nr>) during recording Keyword Test. It isn't proper because in the next turn loop of Keyword Test the number <nr> of chosen position nth-child is changing dynamically (besides the web page looks identically). Solved
