The first thing I will suggest is based on a search I just did regarding finding out what error 2007 is in English.  Try dragging a Button component from the components panel onto the stage so that it ends up in the library and then delete it from the stage.

You seem to be having more issues with components.  I recommend you drag every type of component into the stage like you did with the Button and see if that helps.

[Joselyn6]

Hello Ned.

Precisely had already tried the same experiment with adding a combobox on stage,

but did not work, exist another way that can help?

Thanks for any suggestion, and thanks for your help.

Regards

Did you at any point try to clean things out of your library that you thought you weren't using?  When you use components, they carry a lot of baggage and leave it in the library.

Which component(s) are you actually trying to use in your file, and how do you add them to the stage, using code or by manually planting them?

I will suggest you try removing them all add adding new ones in from the components library.

Hello Ned:

Sorry for the delay, yes I was cleaned things out of the library that I thought weren't using, so I change my code to adding them by code, and remove them adding new ones, there were some errors like this.

"** Warning ** The linkage identifier 'fl.controls.DataGrid' was already assigned to the symbol 'DataGrid' and you can not assign it to symbol 'Component / DataGrid' because the linkage identifiers must be unique."

So I preffer to do a new file, I believe there is no one problem

Just I want to say to you thanks a lot for your great patience and help.

Regards

Joselyn
