stoneridgesoftware: UI Builder Class Not Using the Same Contract as Controller and DP Classes in Dynamics AX 2012
Источник: https://stoneridgesoftware.com/ui-bu...amics-ax-2012/
==============

The other day I had to convert a custom query-based SSRS report within Dynamics AX 2012 into a regular report so that we could run the report from a different form (ProdTable & ProdTableListPage) and have certain values auto-populate the query prompt. Normally something like this would be easy to implement, however, I ran into some issues when making the modifications.

I created the data provider, Contract and Controller classes, and the dialog values were not changing. I ended up building a UI Builder class as well to counteract this issue. I had the logic to pre-populate the contract in the controller class by using the record that was highlighted, and I verified that the values were being pulled into the contract class as desired. I then stumbled across the issue of the UI Builder class was not using the same contract instance as the Controller & Data Provider classes. This was resulting in the values not populating the prompt and were not being passed to the Data Provider class. What I wound up having to do is to move my logic into the UI Builder class. Below I have the code I had to do in order to utilize this.

Controller main method:

public static void main(Args _args){ SSI_DemoController controller = new SSI_DemoController(); SSI_DemoContract contract = new SSI_DemoContract(); controller.parmReportName(ssrsReportStr(SSI_DemoReport, Report)); controller.parmArgs(_args); controller.parmShowDialog(true); controller.parmShowReportViewerParameters(false); controller.startOperation();}The rest of the logic had to be put into the UI Builder class, specifically the build method

public void build(){ DialogField dlgItem; Args args; ProdTable prodTable; SRSPrintDestinationSettings printSettings; controllerDlg = this.controller(); contract = this.dataContractObject(); args = controllerDlg.parmArgs(); controllerDlg.parmReportContract().parmRdpContract(contract); if(args.record() && args.record().TableId == tableNum(ProdTable)) { prodTable = args.record(); contract.parmItemId(prodTable.ItemId); contract.parmNumberOfCopies(prodTable.QtyCalc); } printSettings = controllerDlg.parmReportContract().parmPrintSettings(); printSettings.printMediumType(SRSPrintMediumType::Printer); if(contract.parmNumberOfCopies() != 0) { printSettings.overridePageSettings(true); printSettings.overridePrintContractSettings(true); printSettings.numberOfCopies(contract.parmNumberOfCopies()); } dlgItem = this.addDialogField(methodStr(SSI_DemoContract,parmItemId),contract); dlgItem = this.bindInfo().getDialogField(contract,methodStr(SSI_DemoContract,parmItemId));}This code was able to solve the issue I was having and should help you if you’re facing the same problems.
