UIBuilder: "The data source is not embedded within a (parent) data source." Error For Doing a Parameter Lookup

Hello awesome community!

This is my first take on using UIBuilder, so please correct the newbie!

I want to have a lookup in a parameter, Table name: "PurchAgreementHeader" Field Name: "PurchNumberSequence".

The drop down button appears next to the parameter field, but once I click on it I get this error saying: "The data source is not embedded within a (parent) data source."

I believe the issue is coming from the lookup method, so here how my lookup method looks like:

public void lookup(FormStringControl _control)
{

    Query                   query = new Query();
    QueryBuildDataSource    qbds;



    sysTableLookup = SysTableLookup::newParameters(tableNum(PurchAgreementHeader), _control);
    sysTableLookup.addLookupfield(fieldNum(PurchAgreementHeader, PurchNumberSequence));

    sysTableLookup.addSelectionField(fieldNum(PurchAgreementHeader, PurchNumberSequence));

    sysTableLookup.parmQuery(query);

    sysTableLookup.performFormLookup();

}

Is there something wrong in the lookup method?

Any advice would be appreciated :)

Thanks in advance!

Hi Momochi,

For future question, would you mind to use keywords in the tags, not complete sentences? I have cleaned it for you.

this line empties your query, I guess

sysTableLookup.parmQuery(query);

Hi Momochi

The problem is that your query has nothing in it.

You initiate the query, but then you do nothing with it.

You should at least add this second line of code:

Query query = new Query(); query.addDatasource(tablenum(PurchAgreementHeader));

You should then add any other line of code you need to manipulate the query. But that'll get you started.

It did solve my issue!

I thought this line :

sysTableLookup = SysTableLookup::newParameters(tableNum(PurchAgreementHeader), _control);

would add the table to the query but turned out i'm wrong and I need to use the line you suggested to add the datasource to the query.

Thanks alot!
