There have been a few small issues running APEX 5 applications in Internet Explorer since the initial release last year, but most of these have been ironed out in subsequent patches. The issues usually come from Internet Explorer handling CSS in a different way to the other main browsers.
One particular issue I came across that fell into this category was when including a maximise button on a sub region. In the example below we have a number of regions inside each other
When I maximise the report region in chrome, it looks like this:
The region isn’t rendered properly due to the way that IE processes the CSS. I created a support ticket with Oracle and was told that this issue wasn’t feasible to fix due to this being an issue with Internet Explorer and not APEX (despite Internet Explorer being listed as a supported browser for APEX).
This isn’t something I can really say to customers so I had to fix it myself – here’s what you can do if you encounter this error:
This should be documented in a future APEX release – the official word from Oracle was “Don’t use the maximise button in sub regions” but if you play around with the region template like I did you might be able to get it working on a case by case basis.
