Posted on by Tool Consulting 25

Hello,

I want to make a contract parameter with MultiSelect, when i open dialogs for the first time, it's open without problem, but in my case I have to filter the multiselect based on another parameter contract, and so when I choose the value in the field on which I'm basing to filter the multi select and I open the lookup it gives this error 

"A control with the name 'Fld1_1_Ids' already exists on the form"

and error un this line

SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(), WMSAisleIdDialog.control(), query, false, selectedFields); 

and exctly in this control WMSAisleIdDialog.control()

thank you

    Moved from Microsoft Dynamics AX Forum to Dynamics 365 Finance Forum.

    As I said, you should call constructWithQuery() just once. You already seem to have a class-level variable for it (ctrlWMSAisleId).

    When you want to use a different query for ctrlWMSAisleId, you can set it by calling refreshQuery() method. For example:

    public void lookupAisle()
{
	Query query = new Query();
	QueryBuildDataSource qbdsWMSAisle = query.addDataSource(tablenum(WMSAisle));

	qbdsWMSAisle.addRange(fieldNum(WMSAisle, InventLocationId)).value(queryValue(strInventLocationId));
	qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, AisleId));
	qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, InventLocationId));

	if (ctrlWMSAisleId)
	{
		ctrlWMSAisleId.refreshQuery(query);
	}
	else
	{
		container selectedFields = [tableNum(WMSAisle), fieldNum(WMSAisle, AisleId)];
		ctrlWMSAisleId = SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(), WMSAisleIdDialog.control(), query, false, selectedFields);
	}
}

    public void lookupAisle()
    {
        Query					query		    = new Query();
        QueryBuildDataSource    qbdsWMSAisle     = query.addDataSource(tablenum(WMSAisle));

        if(strInventLocationId)
        {
            qbdsWMSAisle.addRange(fieldNum(WMSAisle, InventLocationId)).value(strInventLocationId);
            qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, aisleId));
            qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, InventLocationId));
            
        }
        else
        {
            qbdsWMSAisle.addRange(fieldNum(WMSAisle, InventLocationId)).value("");
            qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, aisleId));
            qbdsWMSAisle.fields().addField(fieldNum(WMSAisle, InventLocationId));
        }
        

        container selectedFields = [tableNum(WMSAisle), fieldNum(WMSAisle, aisleId)];

        ctrlWMSAisleId = SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(), WMSAisleIdDialog.control(), query, false, selectedFields);
    }

    Yes, i'm in D365 F&O.

    and Yes yes I am based on the value of a parameter to filter the multi select lookup. so i change the query.

    please where can i use refreshQuery();

    Which version of AX is it about?

    Constructing SysLookupMultiSelectCtrl again sounds wrong to me. If I understand this correctly, you want to change the query and you should use refreshQuery() method for this purpose. It's available in F&O, at least.

    By the way, let me change the category from Other to Development / Customization / SDK.
