Can you show us a simple test case so we can see how you're defining your DataView. Ideally condense it down to a minimal EntryPoint class we can run on our end.

Thanks

Actually - to follow up on this: The dataView class was designed for a very specific set of requirements (involving loading web services), and the implementation is tailored specifically to that particular use case. dataViewLoaded() is a very specific advanced API tied in with the component, and very unlikely to be an API you need to hook into within your application.

Can you let us know exactly what you are trying to achieve and we will let you know what approach we would recommend.

I definitely appreciate the quick replies. Maybe it would be better not to try to debug a feature I really would not need.

My intent is to separate the login logic from the application logic. Maybe I am solving a non-existent problem. I want the login 'application' to load fast. In fact, I might want to have more than one place where I embed login logic.

My product has 3 levels of users. Each level adds to, and permits the use of the application functionality of lower levels. In terms of population, I anticipate each higher level will have an order of magnitude fewer than the one just below. I figure I can subset the applications and load just what users need for reasons of load times, and potentially, security.

Once the user has been confirmed as valid, and their type, then I only want to load the specific product application appropriate to their type.

My plan was to have the login logic open an appropriate application that would take over the browser window. This would require passing parameters to the new application that would authenticate the link and pass data on the user with which to open the new app so that their current data could be presented to them.

My attempt was to use the dataViewLoaded event to retrieve the passed parameters and pass it to internal controls.

I am not stuck on using a dataView at the start.

Any guidance would be appreciated. I can test my current app on remote servers. From the run logs, they seem to be in Russia and I notice a significant delay in loading. This may be amplifying a non-problem.

Thanks,

Rick

dataViewLoaded is definitely the wrong event for this - again it's related to WSDL/schema and doesn't apply to your app.

Normally if you have some actions you're going to take when the application starts up, you just put the appropriate JavaScript calls (to open a login window or whatever) at the beginning of the app.

I was hoping to use a simple stringmethod to effect the parameter receipt. The reason is that the application is still fluid and being maintained in VisualBuilder. This has been a wonderful SmartClient tool from the beginning. And, I have not yet been ready to cut over to JavaScript just yet.

I have had to revert to JavaScript for some workarounds and testing. So, I know I can do it. There is just some more work in VB I need to do before cutting it loose. Maybe, doing the login coding will have to wait for that. My preference would have been to do a simple login stringmethod now to maybe simulate a more secure one later.

I am open to some other SC object and event. I tried visibilityChanged on a number of them to no avail. Maybe, y'all know how to force that event to trigger at the beginning.

Meanwhile, I happily chug along with other stuff. I really enjoyed getting back to this project after a number of weeks off.

Thanks,

Rick

There is no appropriate StringMethod that appears on any arbitrary component, but Component XML can include method definitions that call Super(). So you could override draw() for example and call Super() after taking some other action.

See the Component XML overview for examples of embedding methods in XML.

After some consideration, I have decided to abandon my early effort to separate the login logic from the business app. The right time to do that might be when I leave the comfort of VB and launch into the vast darkness of JavaScript.

I just added a window at the beginning of the app that picks up an email address, etc., and primes a half dozen forms and lists on tabs that will appear with the main window when I show it.

It was easier to do than I figured. I might find a use for your login dialog widget later.

Thanks for all the help. It was all useful.

By the way, I have been launching my servlet and producing PDF files with iText from the databases recently. They are looking great and I am now getting them under control of print options off dialogs transmitted using valueManagers. It works great. I give you credit, but I still think it is magic.
