Error "Control <name> has no parent window"

[mait]

I have been previously able to place CGDev JQ components onto my forms. Now when I try to add any of the following components:

TIWCGJQEdit, TIWGCJQButton, TIWCGJQDatePicker, TIWCGJQSlider, TIWCGJQTreeView, and many others, I get the error message:

"Control <name> has no parent window."

Other components, such as:

TIWCGJQLabel, TIWCGJQDialog, TIWCGJQRegion, TIWCGJQCheckBox, TIWCGJQRadioButton and many others, drop onto the form OK.

I can copy and paste an existing label, button, etc. but I can't drop a new one onto the form.

I don't recall doing anything in particular prior to the problem occurring. I have reinstalled IntraWeb and CGDevTools IWJQuery suite and created a brand new Intraweb project but the problem remains.

Anyone have any ideas as to what's gone wrong?

Thanks

IWJQuery Suite 2.4.0.119
IntraWeb 14.0.36

Hi

I'm sorry, but we cannot reproduce this.

Can you reproduce this in a simple application.

Or, can you send us the form where that issue is happening?

Thanks for the reply Jorge.

I'm not surprised you can't duplicate it. I don't think it has to do with your components as such. I was hoping that someone else (smarter than me) may have experienced this and worked out the solution.

As I mentioned, simply creating a brand new Intraweb app and dropping a button or edit box onto the form generates the error so something must have changed in my development environment. I was hoping that there was something common to ...Edit, ...Button, ...DatePicker, ...Slider, ...TreeView, etc. that was not common to ...Label, ...Dialog, ...Region, ...CheckBox, ...RadioButton, etc. that might give a clue as to why some components work and others don't.

Thanks,

I report the same problem, same Intraweb version and Cgdevtools version. My Ide is C++Builder XE3.

It seems, if you have the disable render option, you get the error.
If you enable render, it works.

Hi Niccolò. Problem fixed. Thanks for taking the time to post the solution.
