issue when creating a webform that has FNCchecklistbox sitting on it

Hi Bruno,

I put a panel on the main form and would like to create a sub-form that has a FNCChecklistbox onto the panel. The first time when I clicked the button creating the sub-form, it works.

Code inside the button click event used to create form:
if assigned(Form2) then Freeandnil(Form2);

However, if I click second time to create the sub-form again, there is an error saying :

ERROR Uncaught TypeError: Cannot read property 'src' of undefined

On the other hand, if I remove FNCchecklistbox from sub-form, there is no problem.

Here is the main form :

And sub-form :
Error as I can see :
Here is testing project :55. Checklistbox (2.3 MB)

Thanks for your help!
