[mir-coders] Problems with nested utility functions in templates

[briganzia-informatica]

Hi,
I use nested utility functions  on my startpage.template to get the first 
500 chars and strip off html tags 

...
<list myvarsfromtemplate as h>
<assign cont=h.content_data>
${utility.subString(utility.regexpreplace(cont,"<(.|\n)+?>",""),0,"500")}
...
</list> 

If I use that nested function out of cycle it rules well, but if I use it in 
<list..> </list> Mir fall in a loop and exhausted all available memory, even 
if I try to split my nested functions and use them separetely
Of course that cycle without nested functions rules well...
So, what I'm doing of wrong? 

Thanks in advance
