HTMLB button - Variable as property

Hi at all,

how can i get a variable as a property of a htmlb-button?

In the layout of the site i do a loop over the table to show the data. For each position i should have a button to show a document for this entry. Caused by the layout of this table i cannot use a tableview.

But if i use this htmlb button and use the documentnumber of the entry as the id of the button without " i get the message: "The property must have a value."

If i use "wa_res-documentnumber" as property the value of the property is wa_res-documentnumber. So i cannot use this, too.

So i think a variable cannot be used as a property.

I should have the documentnumber of the entry to handle this entry in the eventhandler OnInputProcessing.

Any other ideas instead using the id of the button?

Thanks and best regards,

Timo
