Ok it works.
I only have one probleme.
If i edit a row in the form it shows me the right value of the first select field but the wrong value of the second depended select field.
In the second select field it use the first entry.
If i use the buttons next i get the next row and the right value for the second select field.
colModel :[
{name:'projektname', index:'projektname', width:160, sorttype:”string”, edittype:”select”,
