Extension help

[ProfMarks]

I have successfully built an extension that uses the vehicle template and adds a desktop icon to call up the custom window. I have been able to fight through all the problems with the exception of one, and I'd appreciate any insight the experienced coders could lend.

At first test, everything works great. However, on the main tab, where a vehicles description resides, I'm encountering a small problem.

When adding a new item, the default empty position text displays, I can click on it and edit the test as desired. I can close down the window, bring it back up and do the same. However, if I leave the campaign and return, any items entered previously do not allow me to enter new text into the description box and the default empty position text is gone.

If I previously entered information, I can edit it using the edit text from the menu command, but what I'm faced with is if someone doesn't enter something in the description text field during the current session, they will be locked out from doing so later on.

Thanks ahead of time.

Hey ProfMarks, its hard to say exactly what the problem is without seeing the source for your extension. Can you post up the windowclass defintion and any associated LUA scripts and well see what we can do.

From the description you have given it might be a database node ownership issue, assuming this is a client accessible window.

Thanks for the help offers:

OK, given the forums have mashed the formatting, this is probably going to be easier to do if you attach your extension to a post as an attachment. I can then download it and take a look.

BTW. I noticed a few whitespaces in the middle of variable names like old node or ol dnode instead of oldnode, I assume this if the posts formatting thats done that but thought I should check just in case.

If you can't attach the extension, let me know and I'll PM you my email address and you can forward it that way.
