Re: logic tag - to check form elements
Hi Raghu What's the name of the form bean? Let's assume it's "myformbean" for the example: ... Use the 'name' parameter to reference the form bean name. Use the 'property' parameter to reference the property. Note, you will be testing the value in the form- bean, not the value in the hidden html field. Do you need to change the value of the hidden field? If so you will need to use Javascript to perform this test and modify the displayed values.

If you want to update HTML page without submitting it to the server, then use some Javascript. If you submit form each time an operation is changed, add an "operation" field to your form bean and use when you re-render the HTML page.

logic tag - to check form elements
I have a hidden html varibale called operation. Now I want to conditionally display some buttons based on the value of this hidden field. I am trying something like this... # display update related buttons This doesnt seem to work. What am I doing wrong? I know that if 'operation' was a variable is request/session then it would work fine. But what should I do if operation is a html form element (hidden). I do not want to write scriptlets. Thanks. Best Regards, Raghu
