Using variables in a URL call

Question

APEX version = 4
- DB version and edition = 10g
- Web server architecture = OHS
- Browser(s) used = I.E. 8
- Theme = #5 opal
- Templates
- Region/Process type
Hello
I am trying to call a report from another environment using a url, if I enter the following in my application or just in IE with a hardcoded value "54-123" is works
http://xxxxxx.xxx.xxx.xx.xx/ReportServer/Pages/ReportViewer.aspx?/DDB/Charles237&rs:Command=Render&IN_CS_BOX_XCODE=54-123&rc:parameters=false
If I try to use a value off of my page the browser does not get the value in the page item :P7_CS_BOX_XCODE but takes the name as the value.
http://xxxxxx.xxx.xxx.xx.xx/ReportServer/Pages/ReportViewer.aspx?/DDB/Charles237&rs:Command=Render&IN_CS_BOX_XCODE=:P7_CS_BOX_XCODE
&rc:parameters=false
How can I make this call using a dynamically changing page item?
Thank you in advance for any help.

Answer 1

The URL reference for the item gets replaced with the item value from the session.
But since you said you don't see the items value in the session though you can see it being displayed, it is being set after the page loads and is not yet passed to the session.
The most common reason why this happens id when you use the "Source" or "Default" properties of the item to set it a default value. If this is the case remove that and add an onload PLSQL process that sets the default value of the item. This would make the item value available in the session for apex to substitute it correctly ion that link.
Hope it helps.
