TdwsStringList problem with dangling Interface reference

[Josef Kučera]

Hello, I have discovered a nasty little problem with the TdwsStringList.InsertItem() implementation. Adding items with objects, deleting any item from the middle and adding another item causes access to a dangling Interface (it was left there by raw the move of elements). The fix is quite simple (the string reference is already correctly cleared), patch attached.

Thanks!

This unit and the dwsClasses module are rather unused (here) and untested. As you are using them, if you have any ideas for basic units tests so it is at least minimally covered, these could help in the long run!

You are welcome!

I have just started to use the dwsClasses module. Unfortunately right now I do not have any ideas for unit tests yet. I will definitely share them (tests/ideas) if/when I do have some.
