[CLOSED] Error when da DataSource of GridPanel.Store is empty (datareader datasource)

[supera]

I am trying to do a generic search control...
For this, I follow two examples:

Grid and Store reconfigure
https://examples2.ext.net/#/GridPane...e_Reconfigure/

and

System.Data DataReader
https://examples2.ext.net/#/GridPane...ta/DataReader/

It's working beautifully if the datareader contains records... but if datareader returns empty, a error occurs.

Attachment 3790

The result.script contains this text:

SuperaWeb.SGAC.Dividas.wndDividasDetail_wndEmpresasSGE_sdtCidade_storeSearchData.proxy.data = ;SuperaWeb.SGAC.Dividas.wndDividasDetail_wndEmpresasSGE_sdtCidade_storeSearchData.load();

The search control code is very complex. It's a little hard for me to have a working example...

So I'd like a hint of what I could do when it comes dataReader empty ... some value that I can set to Store.DataSource or something

Thanks for any help.
