[TYPO3-mvc] FLUID: check checkbox by array

[Daniel Lorenz]

Hello,

I trying to check a group of checkboxes in Fluid-template specified by
an two dimensional array myarr[x][y].

The x and y are the uids of two Objects "Cols" and "Rows".

In ExtbaseCheatSheet I found {name.number} for an array but
{myarr.row.uid.col.uid} doesn't work and thats OK.

I tryed alias the row.uid and the col.uil with

<f:alias map={srow: row.uid, scol: col.uid}>
  {myarr.srow.scol}
</f:alias>

Can anybody help me?

Thanks a lot,

Daniel
