Hi,

 

yes you can compute the databindig, but you have to do this in "OnPageLoad"-Event:

 

 

Hi Sven,

 

I dont think this is gonna work since I use a compositeData.requestVar variable to determine which object I need to grab from the requestScope. This is done because the custom control is 'dynamicly' loaded using a repeater. On each iteration the repeater defines which data object is should create ( java object). This object stores data about the current field (value, name, type etc). With this information the correct custom control is being loaded. When add stuff ot the onpageload event the data needed isn't there yet I think therefore it fails with an exception. Is there a way to bind a control to the request map that is being constructed when a post is done? 

Hi Sven,

 

I cannot find the onpageload event do you mean the beforepageload event??  When I try to retrieve the compositeData var in the beforepageload event I get an error it cannot find the var I'm asking for. I think this is due to the fact that the control is being loaded from a repeater?

Hi,

 

this is not a event, it is a definition how the value is rendered:

 

 

If there is a # before the value will be computed every time the label is refreshed.  If there is a $ the value is computed if page is loaded. The last one is always executed before the dynamically computation. That is why you can compute a binding "On Page Load" which then is binded dynamically (what I have wroted before: "the $ is the key").

 

Hope this helps

Sven

Hello Sven,

 

thanks I already new the difference between # and $ but got a bit confused since you wrote "OnPageLoad"-Event:" .

Oh, Sorry for that. Have you tried to use a data context for your objects?
