RE: Prevent CFTREE Refresh Upon Return to Page
You could put the results of the cfc call into a session or some other persistent variable, then check in the code if it is set. If it is don't fire the cfc, if it isn't fire the cfc. This of course is just a possibility since I don't know what is actually going on or if the data is of a type that can be persisted. -Original Message- From: Dana Kain [mailto:dana_j_k...@rl.gov] Sent: Thursday, January 12, 2012 9:42 PM To: cf-talk Subject: Prevent CFTREE Refresh Upon Return to Page I have a form containing a CFTREE bound to a CFC. Users can expand the items in the tree and click a submit button, which takes them to another page. They then use the IE8 browser back button to return to the CFTREE page.

Re: cftree Refresh
Hello,
I'm trying to do a refresh to a CFTREE, but an error appears in the console:
-
Error: _6a.parent has no properties
Archivo de origen: http://192.168.1.5/CFIDE/scripts/ajax/package/cftree.js
Línea: 219
-
This is my form:
cfform name=form_navegacion
cftree name=NavTree format=html
cftreeitem bind=cfc:dirtree.getDirEntries
({cftreeitempath},{cftreeitemvalue})
/cftree
input type=button value=Refrescar onclick=refresh(); /
/cfform
And this is my JS function:
function refresh() {
ColdFusion.Tree.refresh('NavTree');
}
Somebody could make this work? I think I'm doing something wrong
Thanks in advance!

Did you ever find the solution to this issue? I'm having the same problem with cftree refresh . . . The CFC returns the data correctly.

Re: cftree Refresh
Thats my doubt... because in the CF8 Documentation, in the ajax Javascript
Functions appears this sintax:
ColdFusion.Tree.refresh(*name*)
2007/8/3, Brian Kotek [EMAIL PROTECTED]:
What exactly do you think is going to happen when you click the refresh
button? Because all it is doing is calling refresh() on the grid, no data
is
being passed or updated, so I would think you wouldn't see any change at
all.

Re: cftree Refresh
I tried it (using Forta's dirtree CFC, and it didn't work for me
either. I don't know why it's not working - it is finding the
tree.js. I know that's not very helpful. Sorry.

Re: cftree Refresh
Good Question. Bruno and I both are getting the javascript error he
indicated, and I don't think that's supposed to happen. I was kinda
thinking that it would reload the root nodes, but I haven't really
thought it through. I just tried it because I recognized it as a
modification to Forta's example,, was curious abuout the
ColdFusion.whatever functions, and to see if I could maybe help Bruno.
You've got a good point about the refresh.
