<htmlb:link> with target-attribute

Hello,

I want to use the htmlb-tag <htmlb:link> with the attribute target="_blank" to open the target-page in a new browser-window. I did the following coding:

...

<htmlb:link id = "idLink"

onClick = "showDetails"

reference = "./detail.htm"

target = "_blank">

<htmlb:image src="./s_bgmore.gif"

alt="details"/>

</htmlb:link>

...

But the new page opens in the same frame. Without the "onClick"-attribute a new window opens, but the server-site eventhandler "onInputProcessing" is just processing when the "onCLick"-attribute is set. And I need this eventhandler to select data before calling the next page.

The online-docu says that the target-attribute is just regarded if an HREF is set. How can the problem be resolved?

Thanx for all hints,

Mathias
