Summary: Dynlayer.js elm error, NS4 + IE5, R2.56
Initial Comment:
When I attempt to use DynAPI.document.addChild to add a layer, I get 'elm' errors in
both
NetScape (4.76) and IE5
NetScape error dynlayer.js line 103 elm has no properties.
IE error line 91 'elm.style' is null or not an object
Basically, I have two parts to this, which are both generated by the same code. The
'StdLayer'
code completes OK, the 'StdEditLayer' code completes with the error. As soon as I do
anything
after this in NS, the application crashes out. I'm running release 2.56.
I can't see what I have done to get this situation. Any pointers you could give me
would be much
appreciated. I have to admit that this was working, but I can't find out what I have
done to stop it
from working.... :-(
PS. The application displays a tabbed page, where the users can click on the tabs to
display
different information. Everything works fine for the read-only displays, but the
editable information
fails.
StdLayer = new DynLayer( null,0,0,PageWidth,PageHeight,null,false,10 );
StdTFLayer = new TableFrame( TableFromX,TableFromY,TableWidth,TableHeight,
StdHTMLNoEdit
);
StdLayer.addChild( StdTFLayer );
var TabX = (TableWidth/10) + TableFromX;
StdLayerTab1 = new Tab( TabX , TableFromY , 100 , TableWidth/8 , null , 'Standard',
'' );
StdLayer.addChild( StdLayerTab1 );
TabX = TabX + TableWidth/7.5;
StdLayerTab2 = new Tab( TabX , TableFromY , 98, TableWidth/8 , null , 'People
Tracker' ,
'DisplayLayer("PTrack");' );
