DCDataControl.isTransactionDirty() return true incorrectly

Question

Hi,
My page is based on EO based VO and there is a view criteria build on the VO which become a search panel in the page.
When user first come to the page, unless they perform a search, there is no result display in the page. And after user search, they can start modify the record in the down table. In the bean, I use DCDataControl.isTransactionDirty() to see whether there is pending changes in the page.
However, after page load, before perform any search and modification, DCDataControl.isTransactionDirty() already return me True, which is wrong.
Below code return true:
BindingContext.getCurrent().findDataControl("PullSequenceSetupAMDataControl").isTransactionDirty();
While below code return false:
BindingContext.getCurrent().getDefaultDataControl().getApplicationModule().getTransaction().isDirty();
I cannot rely on the AM.getTransaction().isDirty() because I have transient attribute on my page, when user change those, I want to consider it as pending changes as well so I have to use the first one, but somehow it return me weird result.
However, I have no idea, why isTransactionDirty() return my True (dirty) even there is no records shows up on my page? Right now, I have to either issue a "commit"/"rollback" from my page, then isTransactionDirty() return my false (clean).
So please do let me know in what condition, DCDataControl.isTransactionDirty() is consider as Dirty??
Some point that I suspect that making this issue happen is:
My VO contains a required bind variable which need user input at run time. So actually after page load, there will be a popup promt for user to enter the value for this bind variable. Seems like after this, transaction start becoming dirty. Please let me know whether this flow will impact how DCDataControl.isTransactionDirty() is working
I am using Jdev 11.1.1.3.0
Thanks.

Hi, Thanks for your reply. However, it is not what i am asking, my scenario is:
I have one jspx page which include mutiple tabs(Panel Tab), each tab actually has its own taskflow and its own jsff page. And each tab has its own data control also.
However, we only want to check pending changes for one tab only. And that is why instead of using DataControlFrame.isTransactionDirty(), i am using below code to get the specific data control that used in the tab that want to check pending changes :
BindingContext.getCurrent().findDataControl("PullSequenceSetupAMDataControl").isTransactionDirty()
However, I don't have any action on this tab yet, some action on other tab somehow make all the data controls in every tab dirty. And that is why causing the trouble. And when click the cancel button on my tab(which is rollback icon I drag and drop to the page from my data control), it did reset all the data controls of all the tab back to clean.
My questions is more like:
Why does other tab that is not using my data control can make my data control dirty? Does datacontrol.isTransactionDirty() will be impacted by other datacontrol in the same DataControlFrame?
Is there any setup I need to change so that only action on my taskflow or my tab will change my datacontrol's transaction dirty property?
Also is there any document clearly documented that how datacontrol 's transactiondirty property is maintained?
thanks.
