Dataset values in a masterpage header

Hi,

I have a table with worksets and a parameter to choose one of these worksets.
So I get one row with informations like oid, releasename, comment etc.
These informations I need in the masterpage header. But in the masterpage editor I cant drop tabledata into my header but parameters,varibles and autotext.
Maybe I can get the informations into a variable with a javascript expression? Where can I get some further informations about the "native javascript functions" and "birt functions" in the expression builder?

Someone has an idea?

Take a look at the attached example. It uses a beforeFactory script to swap datasets. It then uses a table with oncreate and onpagebreak scripts to set a pageVariable to be displayed in the header on the master page.

Hey Jason,

thanks for your fast response.
Swapping the datasets works but displaying the pageVariable in your attached example doesnt work in my opinion. All I see is the blue background but not an ordernumber how it was intended for I guess.
Another issue for me is to get these values directly from the dataset without creating a table. Is this also possible? For example in the onFetch event of the dataset?

If you are just doing a preview it will be empty. You have to use the View Report in Web Viewer toolbar action. This is because page variables only work when using a run task and then a render task, which the standard preview does not do.

If the dataset is not bound to a report item it will never be called. Additionally the onFetch order may change if you use aggregates in a table so it is not a reliable place to get the values. If you do not want to show the table just set its visibility to false, which executes the dataset but shows no values in the report.
