Problem with ListBox and deleting ListBoxItems

[SengirPaladin]

Hello

This is my first post and I hope I can explain myself correctly

I am using Carbide Pro, an evaluation version, and I am working with ListBox using the functions of adding and removing elements from it using as a guide the example of the "shopping list"

It works correctly unless the property of Markable List of the ListBox is modified

In that case, Items can still be added to the ListBox, buif it is tried to remove one of them, I receive a Panic; E32USER-CBase 21

The line that has problems and the one used to remove items is this one:
((*CDesCArray) Model->ItemTextArray())->Delete()

Just like using another which is very similar:
model->SetItemTextArray()

But I have checked the index of the ListBox and it is between the limits of the used array

You may find something in Listbox example of 2nd edition S60 SDK-s. It contains markable list (although I do not know if it removes elements from it).

I have been doing some test with new Projects, changing the Markable List Option
But I could not make any progress
I only could notice that the function:
DeleteSelectedListBoxItemsL( CEikTextListBox* aListBox )
which is auto-generated by Carbide, has the same error

I hope that this server you, so somebody can find a way to fix it

it might help to check the SDK docs: "This panic is raised by any operation which accesses an element of an array by explicit reference to an index number, for example, the Delete(), InsertL() and At() member functions or the operator Operator[]. It is caused by specifying an index value which is either negative or is greater than or equal to the number of objects currently within the array."

So have a look into your index values and that they are on the range, also remember that the indexing starts with zero, thus the last one is Count() - 1.
