The simplest way to enable/disable the Finish button on a Wizard form called from a SysWizard class is to retrieve the FormControl object from the FormRun object using the FormControlId and then set the Enabled property based on the your test condition, such as whether another FormControl contains a value. There are many ways to implement this. I'll provide two examples.
In the first example, all of the modifications are done on the Wizard Form.
A FormControl is used that can be called like any FormControl that has the AutoDeclaration property set to Yes.
In the second example, I'll override the finishEnabled() method on my Wizard class, so it behaves in the manner that was expected.
In each example, the formControl is found using the FormControlId which takes the control's label text ("Finish") as the argument. I found the correct Label ID by doing a "Lookup Label/Text" on "Finish" in the code editor and then selected the SYS label with "Label for Finish button in wizard" in the label's Description.
Example 1: FormControl object on Wizard Form:
In the Form classDeclaration add the following:
class FormRun extends ObjectRun
{
//FormControl objects used to get SysWizard Finish Button
FormControlId finishButtonId;
FormControl finishButton;
}
Initialize the new FormControl in the top level Form init() method:
void init()
{
super();
if (element.Args().caller())
{
sysWizard = element.Args().caller();
}
finishButtonId = sysWizard.formRun().controlId("@SYS302811");
finishButton = sysWizard.formRun().control(finishButtonId);
finishButton.enabled(false);
}
Now you can use the control like you would any other form control. In this case, I'm using the state of checkbox control named IsFinished in my WizardForm as the test condition and updating the FormControl state from the IsFinished.clicked() method:
public void clicked()
{
super();
//set FormControl state based on the current value of the checkbox
finishButton.enabled(this.checked());
}
*Example 2:*Override the finishEnabled() method in your Wizard class:
Note that you'll need to set the default values for the method parameters otherwise AX will throw a compile error because it doesn't match the signature from the base class. For some reason, AX doesn't properly create the method signature. Get rid of the default call to super and replace it with the code below:
public boolean finishEnabled(boolean _enabled = false,
int _idx = this.curTab(),
boolean _setfocus = false)
{
return this.formRun().control(this.formRun().controlId("@SYS302811")).enabled(_enabled);
}
Initialize the control value in the Form init() method:
void init()
{
super();
if (element.Args().caller())
{
sysWizard = element.Args().caller();
}
sysWizard.finishEnabled();
}
Call the class method when your controls are updated:
public void clicked()
{
super();
//set FormControl state based on the current value of the checkbox
sysWizard.finishEnabled(this.checked());
}
