Posted on by Kareem

I am trying to add multi select field to my report

and I did this

My contract class extension

[ExtensionOf(ClassStr(CustAccountStatementExtContract)) ]
final class TRCCustAccountStatementExtContract_Extension
{
    private CustAccount MainAccount;
    private List SubMainAccounts;

    [DataMemberAttribute("MainAccount"),
     SysOperationLabelAttribute("Main Account")]
    public CustAccount parmMainAccount(CustAccount _MainAccount = MainAccount)
    {
        MainAccount = _MainAccount;
        return MainAccount;
    }

    [DataMemberAttribute("SubMainAccounts"),
    AifCollectionTypeAttribute("SubMainAccounts", Types::String),
     SysOperationLabelAttribute("Sub Main Accounts")]
    public List parmSubMainAccounts(List _SubMainAccounts = SubMainAccounts)
    {
        SubMainAccounts = _SubMainAccounts;
        return SubMainAccounts;
    }

}

My try to do the multi select lookup

[ExtensionOf(ClassStr(CustAccountStatementExtUIBuilder))]
final class DYNACustAccountStatementExtUIBuilder_Extension
{
    private DialogField MainAccountField , SubMainAccountFields;

    public void build()
    {
        contract = this.dataContractObject() as CustAccountStatementExtContract;

        MainAccountField = this.addDialogField(methodStr(CustAccountStatementExtContract, parmMainAccount), contract);
        SubMainAccountFields = this.addDialogField(methodStr(CustAccountStatementExtContract, parmSubMainAccounts), contract);

        SubMainAccountFields.lookupButton(FormLookupButton::Always);

        next build();
    }

    public void postRun()
    {
        Query                    query           = new Query();
        QueryBuildDataSource    qbdsCustTable   = query.addDataSource(tablenum(CustTable));

        qbdsCustTable.fields().addField(fieldNum(CustTable, AccountNum));

        container selectedFields = [tableNum(CustTable), fieldNum(CustTable, AccountNum)];

        SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(), SubMainAccountFields.control(), query, false, selectedFields);
        
        next postRun();
    }
}

Is it the correct way to do it?

and also I get this error when I run the report

A control with the name 'Fld2_1_Ids' already exists on the form.

The fields are added automatically, therefore adding them again in your code (by this.addDialogField()) is wrong. Instead, get the existing fields by this.bindInfo().getDialogField() (in postBuild() or in build() below next build()).

When I tried to do this

I get this error when I run the report Object reference not set to an instance of an object.

I also tried to do it in postBuild

When you get an error, your next step should be finding where it's thrown. Very often, you'll then understand what's wrong and you'll be able to fix it, or you'll at least be able to ask a reasonable question is a forum. Please do it now.

Sadly without using (by this.addDialogField()) the parameters doesn't get added I tried to remove them and the fields got deleted by this, maybe because I am making extension of the UIBuilder class
[ExtensionOf(ClassStr(CustAccountStatementExtUIBuilder))]

public void build() { contract = this.datacontractobject() as custaccountstatementextcontract; mainaccountfield = this.adddialogfield(methodstr(custaccountstatementextcontract, parmmainaccount), contract); submainaccountfield = this.adddialogfield(methodstr(custaccountstatementextcontract, parmsubmainaccounts), contract); next build(); } public void postRun() { next postRun(); contract = this.datacontractobject() as custaccountstatementextcontract; ////Customers Name //SubMainAccountField = this.bindInfo().getDialogField(contract, // methodStr(custaccountstatementextcontract, parmsubmainaccounts)); SubMainAccountField.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(CustAccountStatementExtUIBuilder, subMainAccountsLookup), this); if (SubMainAccountField) { SubMainAccountField.lookupButton(2); } }

The multi select lookup is working with this but I am getting this error

RegisterOverrideMethod was called twice for the same object for method 'lookup'. You can only override a method once per instance.

I've been trying to solve this for the whole day but couldn't find any solution.

Oh, sorry, I didn't notice you have extended an existing contract.

I don't think that your new idea to create a multiple-selection lookup without SysLookupMultiSelectCtrl (and using registerOverrideMethod()) is a good one. You need to find and fix the problem regarding SysLookupMultiSelectCtrl, not to throw away SysLookupMultiSelectCtrl and try code that can't ever do what you want.

What happens if you return to your original code and move your code inb build() below next build().
