I have a task to export a repeat grid's content to Excel. I have read an article, but I still can't realize how to properly use it. I tried to repeat article's steps to provide pzRDExportWrapper, but after I click "Save" button I get the error:

Method: Rule-Obj-Activity instance not found: Sb-FW-CTrackFW-Work.pzRDExportWrapper. Details: Invalid value for Activity name passed to ActivityAssembler.

Could anybody give me any suggestions? Thank you.

You invoke activity from another activity which applies to class Sb-FW-CTrackFW-Work. Rule Resolution use primary context Sb-FW-CTrackFW-Work class and try invoke activity pzRDExportWrapper from it and you get error (because rule resolution can't found invoked activity in this class).

Activity pzRDExportWrapper applies to Rule-Obj-Report-Definition class. Try invoke from it.

Try activity step as below:

    Call Rule-Obj-Report-Definition.pzRDExportWrapper

Or use step page for this step which defined as applies to Rule-Obj-Report-Definition class(you can declare it on Pages&Classes tab)

    @o.byelyenov if it helped, please mark answer as resolved. – njc Apr 10 '17 at 16:11
  • Thanks, it helped to remove the issue message, but the export to excel does not work. And also I can't get which page I need to use as step page. – Alexander Belenov Apr 10 '17 at 16:14

    I just resolved your issues. If you want to develop export to excel try to use tracer tool for debug. – njc Apr 10 '17 at 16:20
  • What about step page. I mean that you can direct invoke activity from class `Rule-Obj-Report-Definition` OR can use step page (ex. declare `TempPage` applies to class `Rule-Obj-Report-Definition` and then use `TempPage` as context for activity step where u `Call pzRDExportWrapper`) – njc Apr 10 '17 at 16:23

Okay. I have resolved the issue (thank you njc). I have two sections on a lone web page. A context of the first section is my custom data page Co-Name-FW-Data-Search. The Search page has some single value properties which are initialized by an user via an UI. The second section is a repeat grid section, a report definition as a source. My Search page pointed out in a Pages and Classes tab. Also there is a Page, which is created by report definition and contains results. The report definition takes Search’s values as parameters.

So, I have created an activity and passed the Search page and a Cods-Pega-List MyResultList as parameters. There are some steps in the activity:

  1. Check if Search is null. If true- skip step; else - transfer Search properties into Params props with Data Transform.
  2. Set Param.exportmode = "excel"
  3. Call pzRDExportWrapper with Step Page MyResultList.pyReportDefinition. Pass current parameter page.

P.S.: If it doesn’t work try to play with report definition’s settings.

P.P.S.: An only minus of pzExportWrapper is that it invokes report definition again.
