You asked for it, and we added it. We have so many great developers using ListX right now - it would be best to get some samples straight from the gurus who swear by it. View and Add your samples and tips here!

I am working (testing/debugging) an MS-Access DB i created that you set tables, fields and run it to create an importable LP package.

It creates:
List, Search and Edit modules (used the Hospital tab in the doctor management sample as template).

I promise to share with the community when i am done testing. (been working on it non-stop for 3 days) many tables and logic. (simple VBA)

I just finished the first cut about an hour ago.

Currently when i import the LP i do not get any error. all the modules except the list module are fine. The list module (obviously the most challenging) is empty.
I went through the tab and i could not find what i missed.

Something tells me it is a coma or silly XML tab missing.

Anyone knows a good way to debug?

I checked the log for the modules are empty.

In the Event Viewer in DNN i see many errors (see attached)



Thank you

Are you going to share your Access DB then? I'd love to give it a spin no matter what shape it's in.

Ok, I need your help guys.

I got it to work for a week and it was sweet. finshed a full project with it.

I started adding some validation and stuff.. then i tested it today and i got an error :'''(.
Well.. i do not believe in going back so i would like extra eyes to help me fiding the extact cause of the error that i get when i am installing the LP.


So here we go.

http://symphonyoffire.com/ListX/tabid/368/Default.aspx


I have the sample outcome LP (while gives the error now)

and i have the tool.

emaynard; thanks for your email. yes one of teh hardest parts was the variables length and that weird numbering. But as you see in the code i found a way <img src='http://dnn.bi4ce.com/desktopmodules/ntforums/images/emoticons/tongue.gif' height='20' width='20' border='0' title='Tongue' align='absmiddle'>

I would like to fix and have it available for others to use and improve. If at anytime you find a way to improve pleasse let me know and we will update and share.


Any help is appreciated

Ok, just checking to make sure that is not part of the equation. So you were building installable LPs that worked with DNN 4.5.x and latest ListX, then you added additional code that broke the LP installs.

Have you tried installing any modules manually?

everything else is ok.
i wish the error could be more specific.

The error i get now during installation is:

Failure:
System.NullReferenceException: Object reference not set to an instance of an object. at Bi4ce.Modules.xList.Packaging.Common.CaseLess_SelectSingleNode(XmlNode& SourceNode, String Path) at Bi4ce.Modules.xList.Packaging.Delivery.Tab_Install(PackageItem Item)

During one of the installation steps



Not much os help as to WHERE and what it is crashing on.

Like last time i think i am missing a coma or a tag somewhere... cant find it.. i even tried reversing the changes.. (i still can get the old copy but that had no forms or anything and you would have to fill in directly to the tables ) so not helpful to others,

The DB now is like a wizard , set up teh tables, fields and the layout and voila!

Yeah, it's slick. I'm digging through the individual modules manually right now.

I have a few ideas I'd like to test out if we can get this working again.

BTW - Good job. I just didn't have the patience (or the know-how) to work through the Action length thing.

OK,

So is it safe to say since you had it working before that it has to be something in the validation code?

Also, how far does it get in the LP install process? Does part of it install OK?

I'm asking because I have 4.5.3 and no LPs will install on this without error so I can't see the same error as you.

it installs many things.

65. MyTab.Tab Complete
65. MyTab.Tab Complete
65. MyTab.Tab Complete
65. MyTab.Tab Complete
65. MyTab.Tab Complete
65. MyTab.Tab Failed
Failure:
System.NullReferenceException: Object reference not set to an instance of an object. at Bi4ce.Modules.xList.Packaging.Common.CaseLess_SelectSingleNode(XmlNode& SourceNode, String Path) at Bi4ce.Modules.xList.Packaging.Delivery.Tab_Install(PackageItem Item)

65. MyTab.Tab Complete
65. MyTab.Tab Complete



So it seems to install 5 'Parts' of the tab then fails on the 6th, then installs the other 2..
hmm.. let me see if i can find 8 parts there.

By the way, altho it says complete for the other parts i dont see anything in the portal.
So the failure must have cancelled it

I'll keep digging through the files looking for something that might be causing the failure.

BTW - I posted something in the Blue Sky area relating to having a more descriptive error message for LP failures way back when I first got startedd with LX.

Maybe if others join in a bump that message, perhaps it will get worked into a feature.

we can hope right?

Actually, that was more for just single XML imports, but it's more or less the same idea.
