Added search fld dflt. Now recs automatically displayed, Next doesn't work

Question

I have a page that contains 4 search fields at the top and a report region at the bottom.
I was setting a default for 2 of the fields and when I displayed the page, I would need to click on Go to execute the query and display the report.
Then, I added a default for the 3rd parameter (the 4th still has no default).
Now when I display the page, records that match the 3 defaulted search parameters are automatically displayed, but when I click on Next> , no records are found.
If I click on Go to redisplay the first page and then click on Next> the records are found, however.
I'm new to APEX and don't understand why records are automatically being displayed now.
Can anyone tell me how to turn that off?
Thanks!

Hi Laura,
Yes, the report will always be run unless you have a Condition set that stops this. This is something that is required sometimes.
Firstly, if you need to set a default value for a Select List that is used as a filter for a report, you should do this as a Computation that is run in the Before Header process point and conditional on the value of the item being null.
To ensure that the report is only run when the user clicks the Search button, you have to create a hidden page item (called, say, P1_SHOW_REPORT) that has a default value of 0 (I use 0 to hide the report and 1 to display it - but you can, of course, any values you like). Again, set the default for this using a conditional computation. Now set the report region to be conditional on P1_SHOW_REPORT being equal to 1.
When the page is first loaded, the value of P1_SHOW_REPORT is defaulted to 0, so the condition on the report region would fail and the report is not shown.
Now, in the branch triggered by the Search button, enter P1_SHOW_REPORT in the "Set these items" setting and enter 1 in the "With these values" setting.
I assume that you have a Reset button? If not, create one. This should give you another branch triggered by this button - on the definition for this branch, enter in the page number in the Clear Cache setting.
Now, when the user makes any selection on your filters, the report is not run automatically. However, when the user clicks the Search button, P1_SHOW_REPORT is set to 1, the region condition passes, so the report is run using their selections. When they need to, they click the Reset button - the P1_SHOW_REPORT and the filters are reset to their defaults and the report region is hidden again.
