[TYPO3-english] override if on menu object

[Mikel]

Hi all,

I want to render a section menu with a fluid template when several 
conditions are true.

Therefor I added two new fields as boolean to the database:
1. name_of_field_1
2. name_of_field_2

Now I want to render the section menu (menu type = 3) with fluid if one 
of the two new fields are true.

So I would need an or condition and and override on the cObject.

I tried that way, but without result:

# First, I copy the menu object to a temporary object to attach the 
original cObject if no override should be done
tmp.menuObject < tt_content.menu.20

tmp.myOverride = COA
tmp.myOverride {
     10 = TEXT
     10.value = this has been overwritten
}

# then I override the menuobject into a COA to proove conditions
tt_content.menu.20 = COA
tt_content.menu.20 {
     # now I attach the original resource again
     10 < tmp.menuObject
     10.override < tmp.myOverride
     10.override.if {
         isTrue.field = name_of_field_1
     }
}

The result is, that the original resource is rendered. So my if 
condition seems not to match.

Questions:

Can I override the rendering of a menu type into a fluid template?
Can I check more then just one field in the override condition with "or"?

Thanks in advance

Mikel
