i am sorry, maybe this thread has become so long bec. of me but donT
understand why this happens
<canvas>
<dataset name="localized">
<string name="submit" value="gönder"/>
<string name="reset" value="reset"/>
</dataset>
<button text="$path{'localized:/stri...@name=\'submit\']/@value'}" />
</canvas>
I am just trying this code and see nothing.
