rich:progressBar not updating when maxValue changes

[mdmaurer]

I am using a rich:progressBar to display the progress of a search function that iterates through several categories. I want the bar to show the progress of each category separately, so I have a binding expression on the "maxValue" attribute so it will change on the fly in a backing bean. The value changes properly, and the progress bar continues to work normally; but does not reconfigure itself with the new maxValue. The bar continues to grow at the old maxValue rate. Are we not allowed to change the minValue and maxValue on the fly? Do bean binding expressions like this work on these attributes?

For example:

<rich:progressBar
 value="#testBean.progressCount}"
 interval="1000"
 label="min={minValue}, current={value}, max={maxValue}"
 minValue="0"
 maxValue="#{testBean.myMaxValue}" />

see forum post. checked within RF demo.

progress bar updates it max value in script fine (after it reaches 100 and maximum already changed to 150 it continues polling). But the bar itself shows full on reaching 100 value and only after the value becomes larger - its redrawn with new max.

thanks!

I'm not sure I quite understood your response. Is this a bug that needs to be fixed, or is there something I can do to make it work for me now?

That's a bug. As for now you can re-render progress bar component explicitly.

The explicit reRender works, but does cause an annoying “flash� on the progress bar after every update. I suppose I can live with that for now. Thanks.

[mdmaurer]

Ah, using reRenderAfterComplete instead of reRender gets rid of the annoying flicker…

[mdmaurer]

One other issue I noticed is that when I initially set the minValue to 0, the progressBar will not render as long as the current value is 0. It waits until the current value changes to 1, and then the progressBar becomes visible and shows the progress of 1. Why won't it render itself when the current value is equal to the minValue?
