After putting in several hundreds hours into designing panels in the Designer, I open jBuilder today, and suddenly half my panels show that the dbswing components don't have a dataset displayed in the properties. As a result, the entire panel layout is corrupted (incomplete, missing components) as though there wasn't any datasets attached. Source code looks fine. Compiling and executing the application, everything is correct. Just, can't use the Designer to work on the panels anymore. I saw this happen in jBuilder 2005 when inheriting jBuilder X applications. Ended up having to recreate the applications by copy and pasting the source code from the old project to new files in a new project one at a time. Does anyone have any idea what's causing this and how to reverse the problem? It appears to be an IDE bug, but I can't find anyone else experiencing this.

I checked the Event Log as you suggested, but the last event was on 6/7/06. That was dealt with last week, but unrelated to the current problems. The DataModule Designer is displaying correctly and query tests are all returning Successful. Whatever it is, it's taking killing the display of every text character, including fields, labels, etc. in the panel. I can click on where I know a label is. The object is selected and the properties display correctly. In summary, the obvious attributes of this problem: a) dbswing objects do not display the dataset that obviously exists in the source code, without errors. b) All text in the panels is missing (labels, fields, etc.) Finally, Dialogs are appearing normal. So, it's not consistent across the entire application.

Now, the problem is what to do. With the amount of work done already on our large panels, breaking them up into smaller panels will be a lot of work. Each of the primary panels include 8 to 10 sub panels. (I know what the paradigm criticism is going to be, but, in this case, the client rules) Each of these sub panels will, I presume, require datamodule instances created, where only one was necessary in the primary panel. Since many of the sub panels, refer to objects in the parent panel, such as changing object properties (color, text, content, focus), I'll probably have to create instances of the parent panel in each sub panel to affect these objects. (Maybe I'm wrong, but in the last 5 years I haven't had to do anything like this...convenience and expedience rule over eloquent style in a production environment) Further investigation has revealed that this problem is bound within a project. When switching to other projects in the same run of jBuilder, frames and panels (smaller than the problem panels) are working fine. Once it does occur, it effects ALL panels within a project except those within a dialog. By editing the scope in a dataset query in one datamodule not related to any panels, suddenly, all the panel GUI's fail, irreversibly. Definitely a serious jBuilder bug. Our problem is now in two parts. Short term and long term. I know that Borland has a history of not revealing when an update is going to be released, but maybe, since they are selling off (abandoning!) jBuilder, we could get some hint when the update is coming. Is it weeks, months, quarters? If it's many months away, then we have no choice but to entertain alternate IDE's. At this point, jBuilder 2006 is nothing more than a bloated source editor for us, since most of our work is in database GUI interfaces. In the short term, we have to consider the small fortune in resources we're going to have to expend to reorganize the panels, test and placate the client. Thanks for all the hints. It's a relief to know what is fundamentally happening and to stop chasing our tails. Kevin Dean [TeamB] wrote: Quote: Peter Zaharkiv wrote: Finally, Dialogs are appearing normal.

It's important that you begin running JBuilder from the command line and with the -verbose option. This way, you'll get more input as to what might be going wrong and when. (I don't know that the event log gives you the same info -- maybe it does, but I always run in the -verbose mode.) My guess is that you could quite easily solve this problem by judiciously applying if ( ! java.beans.Beans.isDesignTime() ) { // do querydataset stuff here such as myComponent.setDataSet(qds); } so that you won't be trying to access live data while designing your UI. Have you tried this? It's very possible that something is being instantiated improperly, causing a null pointer exception to be thrown somewhere in the process of building the view in the Designer. Once that happens, it may be that no rendering happens. Quote: Our problem is now in two parts. Short term and long term. I know that Borland has a history of not revealing when an update is going to be released, Few companies release schedules of future updates. It is not a Borland-only phenomenon. Quote: but maybe, since they are selling off (abandoning!) jBuilder, Good grief. Borland and "DevCo" have been very clear that the *tools* are being spun off into a separate company. It is not just JBuilder. And nothing is being abandoned. They have been even more clear that roadmaps to future versions are on track for all IDEs. Quote: we could get some hint when the update is coming. Is it weeks, months, quarters? If I remember correctly, the published roadmap says there will be two updates this year. That's all we know. From my experience, that's a lot more than any other software company has ever published. If you have discovered a bug with the UI Designer -- meaning you can write a small test case which isolates the problem -- file a bug report, and if it affects a significant number of people (i.e., gets a lot of votes) or is found to be a serious flaw with no work-arounds -- the updates may just be able to provide a fix. Quote: If it's many months away, then we have no choice but to entertain alternate IDE's. At this point, jBuilder 2006 is nothing more than a bloated source editor for us, since most of our work is in database GUI interfaces. I'd say there's a better approach -- it's called the "let's roll up our sleeves and figure out a work-around for this" approach. I'm guessing that since it works in simpler examples, you can identify exactly what it is in your large app which triggers this problem, and deal with it without that much effort. The sky isn't falling by any means. -- Paul Furbacher (TeamB) Save time, search the archives: http://info.borland.com/newsgroups/ngsearch.html Is it in Joi Ellis's Faq-O-Matic? http://www.visi.com/~gyles19/fom-serve/cache/1.html Finally, please send responses to the newsgroup only.

The getParent() method will give you the parent (master) panel; all you have to do is cast to the appropriate type. Furthermore, you can access sibling panels as follows (this is from code that I've been using to do exactly that for the last four years): private GamesPanel getGamesPanel() { return (GamesPanel)WindowHelper.getComponentOfClass(getParent(), GamesPanel.class); } Quote: Further investigation has revealed that this problem is bound within a project.

At this point, jBuilder 2006 is nothing more than a bloated source editor for us, since most of our work is in database GUI interfaces. I don't know how far away the first update is, but my personal guess with absolutely no information from Borland is that it will be sooner rather than later (with a commitment to two updates before the end of this year, it won't make much sense for them to be close together at the end of the year). Quote: In the short term, we have to consider the small fortune in resources we're going to have to expend to reorganize the panels, test and placate the client. Welcome to the world of development. Whether it's JBuilder, the back-end database, the Windows subsystem, or a flaky power supply, we've all had to deal with errant problems. I tore some of my rapidly receding hair out today fighting with a poorly documented but absolutely necessary feature in Windows CE. Once you figure out what it takes to extract one panel into its own class, the rest should follow along pretty quickly. Quote: Thanks for all the hints.
