Michał Wojciechowski commented on RF-12236:
-------------------------------------------
The problem is in richfaces.ui.ExtendedDataTable.updateLayout function.
(in
components/iteration/ui/src/main/resources/META-INF/resources/org.richfaces/extendedDataTable.js
file)
When the content is wider than contener following code is executed:
{code}
this.normalPartStyle.width = width + "px"; // rule for width style for all
elements
{code}
and
{code}
this.parts.each(function() { // rule for width style for each
element separately
this.style.width = width + "px"; // overrides previous rule for all
});
{code}
but when countin size of the conten only one of these is executed:
{code}
this.normalPartStyle.width = "auto"; // restoring "auto" rule for all elements
{code}
To fix this following code should be added after previous code to restore
overriding rule as well:
{code}
this.parts.each(function() {
this.style.width = "auto"; // restoring "auto" rule for each element
separately
});
{code}
But rule for each element separately is not needed because it inherits from
rule applied for all elements.
Instead of adding this code following code can be removed:
{code}
this.parts.each(function() {
this.style.width = width + "px";
});
{code}
and the result is similar.

> Re-sizing columns on rich:extendedDataTable breaks horizontal scrolling.
> Note that not all re-sizing activities breaks scrolling, some works properly.
> I was not able to determine which do and which not, as it is same for frozen
> and not frozen columns, and also when re-sizing to a bigger width or smaller.
> It was able to reproduce it on RF from 4.0.0.Final to 4.2.2.Final.
