[TYPO3-mvc] Re: AppendArrayViewHelper

[Nils Blattner]

I had a few points where I had to create different links from the same 
template which essentially had the same arguments except a pager variable.
For that I made this ViewHelper.

Usage:
For the full option list, check the @param's.

<namespace:appendArray array="{someArray}" key="property" 
value="{someProperty}" alias="aliasArray">
	{aliasArray.property}
</namespace:appendArray>

Or inline:

{appendArray(array: someArray, value: someOtherArray)}
would return the merged array.
