Call Javascript From Backing Bean?

[dobreden1]

Hello,

I am tring to open a confirmation dialogue panel from a number of places. The only way I can do this, as I understand, is to call Javascript from, say, a client command button:

javascript:Richfaces.showModalPanel('confirmation');

Is there any way of calling Javascript from the backing bean so that I can pop up these dialogues whenever I need them?

Kind Regards,

Michael

you could use showWhenRendered attribute of modalPanel.

Thanks - I'll try that.

Hi - ShowWhenRendered doesn't work as I expected. I set this to true and created a binding to a backing bean attribute for the 'rendered' property. When I set myBean.modalRendered=true the modal panel doesn't appear.

If I refresh the page I can see it so it seems to be a rendering issue. I tried adding A4JSupport to my modal panel:

<a4j:support event="onshow" reRender="myModalDialogue"/>

But this didn't work either. Is there a way of executing Javascript functions from my backing bean? This would make life much easier.

Regards,

Michael

It's already really simple and many times used successfully by the community.. You just missed the common framework limitation that conditionally rendered components should not be reRendered. Update the parent (like outputPanel).

I don't understand. My modal dialogue is in its own .jspx file and has no parent. Should I wrap it in an outputPanel tag and rerender this?
