can't manipulate imported collection

(0) ShareShare
ReportReport
Posted on by keshamer 58

Hi,

I can't manipulate imported collection.

 

screen 1

I import sharepoint list in a local collection with a button:

simple 

onselect: collect(localcollection;sharepointlist)

this is a simple sharepoint list with only 5 rows for tests. there will be more after and the collect function will filter.

Now go to screen 2

 

screen 2

I show my local cllection in a gallery  and when I click on an element it goes to screen 3

 

screen 3:

made a simple button

onselect : patch (localcollection;gallery.selected;{culumn1:"test"})

 

that doen't works: culumn1 exists, the type is good (simple line of text) and no error occured. Just nothing happen

I tryed:

 

patch (localcollection;lookup(localcollection;ID = gallery.selected.ID);{culumn1:"test"})

Still the same issue : no error, nothing changes

could anyone helps me?

kind regards

    Hi @keshamer,

    Can you share a bit more about your issue ?

     

    I have made a test. There’s no issue on my side.

    Set Onselect property of the button to :

    Patch(collection1,Gallery1.Selected,{column1:"111111"})

    15.png

    Please check if “Gallery.selected” can return the correct value .

    Please check if the default value of the column1 in the collection is blank.  If the default value of the column1 is blank ,you will be unable to update this field .

    This is a known issue at the current time .The same issue link :https://powerusers.microsoft.com/t5/General-Discussion/Bug-Collection-From-Sharepoint-List/td-p/58730

     

    As an alternative, You can use UpdateIf function instead of Patch function .

     

    Set onselect property of the button to :

    UpdateIf(collection1,IsBlank(Gallery1.Selected.column1),{column1:"111"})

    Regards,

    Eason
