Non-standart lookup problem

Hello everybody,

I have a little problem with lookup.

Here I have a small change in the system. On the EDT named ItemId I have a property “FormHelp”.

This property is filled by the name of some Form.

The problem is that this form from some reason works wrong.

Example:

When on the field basen on ItemId we put DC* then we will receive a lookup with Items which names begin on DC.

My form still show all the Items.

I’m tryin to find the class which call forms from EDT property “FormHelp” to send some argument.

Anyone knows which class I can use ?

regards
