Re: [Dynapi-Dev] Large number of updates/fixes

Just been testing what you have currently in CVS. I am using scrollpane and loadpanel and the code is below.

1. In NS4.7 if you resize the browser window with the mouse, (especially making it larger), results in the following error:

JavaScript Error:
http://localhost/dynapi/src/lib/dynapi/api/dyndocument.js,
line 53:

this.children[i].createElement is not a function.

2. MetalScrollPaneURL is not working in NS4.7 or IE5.1 and the default scrollbar images are displayed.

3. The list widget is broken. Produces the following error in IE5.1:

Line:     33
Char:    5
Error:   'css' is not an object
Code:   0
URL:    http://localhost/CFCalc2/washerSelect.cfm

> "precreate" should be used in widgets for doing most of the final layout for a widget as well as setting images for the layers.  Most of that stuff used to be in the "create" event, but now with the inline creation it's more effecient to do it in "precreate" because when you set the size/location/images of the layers you won't be working with true DIV elements rather with just the JS objects.  The goal is to do as little work with div's as possible before you create, so that by the time DynLayer creates the layers it already knows the size and content of them.

The "this.created" flag is now true once the layer/div element is created, and final position/size has been set, AND all it's children are created also.  Peviously this.created was set to true before the children were created which conflicts with the way the inline creation system is supposed to work.  I updated all the widgets to make sure everything was working ok with this change.

I removed all references to getComponent() cause it's not needed anymore.  And DynImage.getImage won't return an Image object with .w and .h tacked on, it's unecessary - if you have any code that uses the .w and .h, just replace it with .width and .height.
