Gii Model generator validates ActiveQuery class even when the ActiveQuery option is not checked

[darksnake747]

I was generating some models for a new project and started out with generating ActiveQuery classes for each. I had defined my own ActiveQuery class extending the yii core ActiveQuery class and placed that class in the ActiveQuery Class textbox on the Gii form under the "Generate ActiveQuery" checkbox/section.

After a handful, I decided to no longer wanted the ActiveQuery classes yet. I unchecked the checkbox and deleted the ones I had already created, including my core. When I tried to generate a model after that, the preview button did nothing. It seemed to be dying silently. Finally, I thought it was maybe that ActiveQuery class field. So I checked the checkbox and that form section was revealed; and sure enough, there was an error message below that textbox saying the class was invalid. The error is correct, but it shouldn't matter if the checkbox is unchecked; the class named there isn't being used.

What steps will reproduce the problem?

1. Access Gii's Model generator
2. Fill in table name and class name fields properly
3. Check the "Generate ActiveQuery" checkbox
4. Type anything invalid into the ActiveQuery class textbox
5. Uncheck the "Generate ActiveQuery" checkbox
6. Click the Preview submit button

What is the expected result?

I should get a "list" of the one model class that should be generated with the option to click the "Generate" submit button to actually create the class file.

What do you get instead?

Nothing "seems" to happen. The form reloads as it was when you submitted it with just the option to click the Preview submit button. However, if you Check the "Generate ActiveQuery" checkbox again, you will see a validation error on the ActiveQuery class field.

Sounds like a bug. Do you want to try fixing it?

I certainly can, may be a little until I get the time to give it; but I'd love to take a stab at helping Yii.
