uncaugh:IllegalArgumentException When I pop a Popupscreen custom?
public class queryPopScreen extends PopupScreen { private VerticalFieldManager contentmanager; private LabelField titleField; private Merchant merchant; private String titleString; public queryPopScreen(String titleString,Merchant merchant) { super(new VerticalFieldManager(NO_VERTICAL_SCROLL | NO_VERTICAL_SCROLLBAR),DEFAULT_CLOSE); this.titleString=titleString; this.merchant=merchant; Background background = BackgroundFactory .createSolidTransparentBackground(6908265, 0); setBackground(background); contentmanager =(VerticalFieldManager)getDelegate(); titleField = new LabelField(titleString); contentmanager.add(titleField); } }
It is the custom code of popupscreen. Pls help me to find the bad code here
I thank you very much.
Yes, the exception was thrown when you try to call popScreen(). I think you try to exit a screen which is not available in the stack screen UIApplication ie., without pushing the screen (by calling pushscreen()), you try to pop (by calling popscreen())

When a pop-up window opens in a new tab, do NOT pass it immediately
Hello.
I changed the value of browser.link.open_newwindow.restriction from 2 to 0. Now pop-ups will open in a new tab instead of new window, which is cool.
But still firefox goes immediately to the ToolTip that gets opened in a new tab.
I want to have firefox in a way that, when a pop-up window is opened in a new tab, do NOT pass it immediately.Note: The option "when I open a link in a new tab, switch to it immediately" in the menu Options-> tabs, is already disabled.
Try to set the pref browser.tabs.loadDivertedInBackground to true on the topic: config page.

Need for a method to be called when the pop-up screen
Hello
I have a requirement in my application. I have a screen from which I'm moving to screen B. When I Pop the screen B, I need a method that must be called in the screen has. Looks same as onActivityResult() in Android.
I am currently using onExpose(). But this method is called for all in the screen has. In the menu click or button also. Is there another way to do this?
Help, please...
You have two options I can think immediately, which do not have to change anything in screen B.
(1) use pushModal when you call B screen. The statement immediately after the pushModal will be executed as soon as B screen is popped. In general, I try to avoid the modal screens, but in this case, it's probably what I would do.
(2) set an indicator immediately before you tap screen B. Test the flag in onExposed(). If the flag is not set, then the onExposed was called for another reason and you can ignore it. If the flag is set, then turn him off and process you want, knowing that the screen that has been exposed as screen B jumped.
Either should work for you.

When the Manager of the custom function in a configuration of link file gets error?
The question she get error when the Manager of the custom function in a config file in the plan to include the link.
When she went to join the custom function Manager in the debugger, everything is OK.
<? XML version = "1.0" encoding = "utf-8"? >
< configuration >
< custom function platform = "DotNet".
library-path="G:\RB1\Include\CustomFunctions.dll".

THS, category and path is correct.
So is there any problem for < custom function platform = "DotNet"?
OPA version 10.2
OPA error message translated from the Germany into English: Exception has been thrown by the target of a callIn general, you should not give the full path of the custom function, it should be rather in relation to the project include file.
for example:
and then make sure that the CustomFunctions.dll file is copied into the project folder until the project is built.
In addition, if you use 10.2 for a new project, the mechanism that you use is now replaced. An extension of the custom function is the new thing, and it will look much nicer when it is used in the rules. Refer to the section 'Write a Custom function Extension' in aid of developer for more information.

If your buttons are the ButtonFields standard, you can create them with the style bit ButtonField.CONSUME_CLICK (possibly in addition to other bits of style, you already specified).

Your problem is that you try to write directly to the valiable that represents your setting. You must use the link which is accessible from the GUI.
And you need to use the action as the event type.

How to add values by default when you add a component customized for fashion design?
I have a set of custom (in general) components that extends spark components. But when you add our custom mode component creation, how can I set defult (in AS3) values.
For example, s:Button default = "Button" label when adding application, or mx:DataGrid has 3 predefined columns, but when you use custom components there are no presets like this.
I can put these values in the constructor, but they are not visible at the time of the design, only run time.
Any ideas? Thank you
Esmin
Yes. Either way, I found the solution. Someone might find this useful.
In the light of the design.xml
Use this
so when you add this component to the design mode, it will be the text value ("ExtendedTextInput" in this case).
