drop down list problem

[nobr]in this code there is a dropdown list.. there is this one item that if you select it, the program goes nuts.. it returns to its home page.. my problem is I cant seem to find where it goes.. i have a hard time tracing it.. my question is if valueChangeListener="#adminController.selectListingLevel}" onchange="submit()"> has something to do with it.. and does the onchange mean it will submit the form?

thanks in advance!

> and does the onchange mean it will submit the form?

The not specific the onchange itself, but the javascript "submit();" means that it will submit the form, indeed.

Also the other form values will be involved in submission.

I am not going to read and debug this big piece of code.

Please cut out all irrelevant parts of the code until you got the smallest possible working example which still reproduces the problem.

And maybe during the debugjourney you will solve the problem yourself ;)

One hint: add h:messages to the form to see if there will be a conversion or validation error thrown from JSF.

ok well this is basically the part where im getting confused..^_^ basically when i select a different value from the drop down list a new page is called it just changes the labels

of most of the textfields.. but when i select the a certain item from the List(the last one) it goes back to the home page.. the original

author of this webpage Im debugging programed it that if an error occurs it will go back to its index.. it says that onchange it will call the submit method.. which calls

<h:form id="general" onsubmit="return check(this);">

check is a javascript function that simply checks whether the fields have been filled up correctly.. so if my tracing is correct im

assuming that it doesnt even get enter the javascript code since i place alerts there to check if was able to get to that part.. so if it doesnt go there, where does it go?.. ..i hate tracing..^_^ thanks..

According to the errormessage the addEditController.getSupplier().getAttachementsSize() isn't available for the expression. Just add a debug breakpoint or a simple sysout to the getSupplier() and/or getAttachmentsSize() and see what happens.
