How do I (and can I) debug a packaged UGI image?

Hi Guys,

I have not needed to use the interactive debugger (I think that's its name) before. I have an odd problem with a GUI image packaged with the "Make Executable" button in the Organizer window. I am doing something a little out side the box. I have a window/form with a bunch of text input fields. Most of which have #editable set to false. Almost all are connected to the result row of a database query. The fields are targets. Based upon data from the row, some of the fields are set to editable. Some of those that aren't have numeric values that in the database are NULL (nil in the field). When the user tabs through these fields a default value is set in the field (usually zero). The two way link (connection) passes this value back to the row and the row seems like it has been changed. When the user closes the window, I check to see if a row was changed and prompt the user to save the changes. If no other changes were made the user is confused by the prompt. I want to avoid the prompt. So, I have written some code that runs the collection of attributes, attributeConnections and break the return connection for those fields that have #editable set to false. This works great in the development environment.

In the packaged image there seems to be a loop that never ends. I'm not sure if a problem is being trapped and therefor no walkback or if it is just a loop. One might think the problem would be in my code that breaks the link but it isn't. The loop seems to by in code that runs over #attributeConnections. I have tried different collection running methods like #detect:ifNone: [], #findFirst: and others. They all seem to never end.

So, I'm thinking I can learn a little more if I can interactively debug my packaged GUI image and that it wouldn't hurt me to learn more about the interactive debugger.

Thanks for any help, ideas, thoughts or whatever.

Lou

Re: How do I (and can I) debug a packaged UGI image?

HI,

Well I solved my problem so I'm not in immediate need of using the interactive debugger but wouldn't mind knowing how anyway.

My problem wasn't in the methods that run the collection as I first thought but was a method (#target) that is in an edit app and therefore wasn't included in the packaged image. I extended #AbtAttributeToAttributeConnection with #theTarget that answers target and get me what I need.

I can now start out with a two way connection for those fields that can sometimes change the database and then break the connection when it is determined that the field isn't allowed to be changed.
