Opening and closing Modal Dialogs from Modal Dialog problem

[LogicTools]

I am trying to combine two modal dialogs.
Clicking on the TextButtons of the first modal dialog should close the current second modal dialog, if any, and open a new one with different options.
It does the task, but after a limited number of times, it closes de current second modal dialog but does not open the new one.
Here is the code, 'my_odcl_dir' should be substituted by the directory where you have downloaded 'FormTest.odcl'.

Any ideas why this happens?

Basically the problem was,
(dcl-Form-Close "FormTest" g_form)
That had to be changed to,
(dcl-Form-Hide "FormTest" g_form)
on all of the TextButton#OnClicked actions.
It is also important to make sure that all the secondary forms are close at the time that Form1 is for the action to be returned to  AutoCad.
Here is the modified code, 'my_odcl_dir' should be substituted by the directory where 'FormTest.odcl' was downloaded.

Hm, thanks for sharing. I had no test, but in my experiences modal forms give no control to AutoCAD for picking points or entities after dcl-form-hide. You have to dcl-form-close before and reopen the form by dcl-form-show again. dcl-form-hide my work with modeless forms, but, as I said, I have no experiencee with that workflow.
