Limitations of the <Select> item

System

Hi,

A quick one here... I have a DCT where I make an inline in order to import data from other DCR's... one of this imports is for a Select Item, which imports values+labels from other DCR, each imported line looks like this (+or-)
<option label="Onbeschikbaarheid van PC banking - Algemeen onderhoud met SD gelijk aan ED (SD SH EH)" value="8" />
Ok, now the problem is that It seems that if I have more than 25 lines, I get an error from the templating editor (as It cannot create a model for this DCT), now, below 26 options, the Template shows up fine...
Now, I haven't seen (or maybe I just missunderstood) any limitation on the number of options for a select.... is it possible that there's actually a limitation????
Thanks for your help!!!
