[TYPO3-mvc] FED - flux flexform grid does not work

[Alexander Dick]

Hi,

I wanted to create a content element with 2 columns, one for text left 
and one for text right. Now I want to have 2 columns in the backend 
element too.

flexform looks like this:

<flux:flexform.grid>
	<flux:flexform.grid.row>

		<flux:flexform.grid.column colPos="0">

                         <flux:flexform.field.text
                             name="textLeft"
                             label="Text"
                             enableRichText="1"
                         />

		</flux:flexform.grid.column>

		<flux:flexform.grid.column colPos="1">

			<flux:flexform.field.text
                             name="textRight"
                             label="Text"
                             enableRichText="1"
                         />

		</flux:flexform.grid.column>

	</flux:flexform.grid.row>
</flux:flexform.grid>

But it doesn't work, the 2 textareas are displayed one below the other.

Am I missing something?

Thanks
Alex
