UiXML and query string parameters

Question

Is there a simple way to access a query string parameter within the destination page?
Example:
- in my source page I have something like:
<link text="My page destination"
destination="page?param1=value1" />
What I want is to be able to acces directly to the param1 within page.uix without handling events or writing any kind of java code.
I have tried to use ctrl:page, ctrl:eventResult or ctrl:servletRequest without success (thought it was not the right thing to do but gave it a try anyway).
As i understand (?) the doc query string parameters are event parameters:
- does it mean we can only deal with query string parameters in an event handler?

Hi Oscar -
As i understand (?) the doc query string parameters are event parameters:
- does it mean we can only deal with query string parameters in an event handler? Right. The UIX Controller allows you to pass data to a new page using URL parameters in one of two ways: as event parameters - in which case you need to have a corresponding event handler - or as page properties. So, the built-in data providers that are supported by the UIX Controller (ctrl:page, ctrl:eventResult) are designed for supporting these two mechanisms.
If you do not want to write an event handler, then you could consider using page properties to pass your parameters. The following link shows how to use the pageURL bound value to construct a destination which includes a single page property:
<link text="Go to target page" xmlns="http://xmlns.oracle.com/uix/ui">
<boundAttribute name="destination">
<pageURL name="targetPage" xmlns="http://xmlns.oracle.com/uix/controller">
<properties>
<property key="prop1" value="value1"/>
</properties>
</pageURL>
</boundAttribute>
</link>
And the following sample shows how to bind to the same property:
<styledText data:text="prop1@ctrl:page"/>
