Thumb rule: EL expressions that look like this are invalid:
${...${...}...}
(unless you have appropriate escapes in place).
Replace with (JSP 2.0):
<c:set var="formProperty" value="id_${counter}" />
Then, the "id" param for your URL is here:
${FAEditorForm.formProperty}
And c:url, c:param will make it cleaner as already suggested below.
