There is a commandButton defined with a visible property as follows:


<ice:commandButton type="submit" value="Test" actionListener="#{DocumentBean.buttonDoDocumentActionOutstanding}" visible="#{DocumentBean.documentActionOutstandingAvailable}"></ice:commandButton>

This button shall become available once a certain condition happens on the server (in my example it happens after a action has completed invoked by a outputResource in its Resource.open() method which is invoked separately from browser to server outside the session). Therefore I use the PortableRenderer.render("..") method as adviced for outside session threads here: http://wiki.icefaces.org/display/ICE/Ajax+Push+-+APIs

So far, so good, With Chrome and Firefox this works perfect and the button becomes disabled/enabled by the push as expected. Unfortunately, it doesn't with IE9.

I did a little bit playing and surprise, if I put the same commandButton there with the attribute rendered=.... instead of visible=... it works with IE.

As visible attribute seems to be implemented by css style switching, it looks as if IE has a problem with that ...
