Hello community,

I have created a gallery within a form.When the screen is visible i created the below

UpdateContext({additemrow:{Brand:Blank(),Model:Blank(),SerialNo:Blank(),Dateofreceipt:Blank(),Recepientsign:Blank(),isEdit:true}});
ClearCollect(CollItems,additemrow);
 
The above creates an empty row to my collection.
My problem is that when i try to create an item via the gallery i get the below error from my patch function.It is looking for an ObjNull type.Can anyone assist me on this?

Hi , in that case I would suggest you something like

ClearCollect(colitems,FirstN(Your_final_datasourcs,0));

By using this colitems will get schema of the your final datasource (no need to manually set the column and it's schema).

Hi @NM-06090901-0, you can't do UpdateContext({additemrow:{Brand:Blank(),Model:Blank(),SerialNo:Blank(),Dateofreceipt:Blank(),Recepientsign:Blank(),isEdit:true}});

you have to do
UpdateContext({additemrow:{Brand:"",Model:"",SerialNo:"",Dateofreceipt:"",Recepientsign:"",isEdit:true}});

by doing this you are defining the type of text for Brand Col previously it Null (Blank so it always expects null object only) in next operations.
instead of sending Blank() try sending empty String ""

Please give the mentioned solution a try and let me know whether it works for you.
If it solves your issue, feel free to mark this thread as answered.
