button to show hidden subform does not work

[Former Community Member]

Hi,



I changed the display property of a subform to
hidden then put in the click event of a button the following code to show the hidden subform:




testSubform.presence = "visible";



Unfortunately, it never works. Weirdly, if I put the same code in the change-event of a dropdown-field, it works.

Also, if I set the subform to
invisible instead of
hidden, the button works as intended, showing the hidden subform.



Here's an example pdf:


button_show_hidden_subform.pdf



Is there a bug with buttons not handling hidden-subforms? Or am I the only one to experience that problem?

Woah, weird, that shouldn't be the case. My best guess would be that it's a bug. If you have a support contract I'd suggest opening a case for this.



I'll try to investigate and post an answer here, but I can't guarantee a speedy response since I don't have an answer off the top of my head.

Hi Chris,



So you were able to reproduce the problem?

Thank you very much, Chris!



I investigated a pretty strange workaround. The following code put in the click event of a button does NOT work to show a subform, whose
presence-property is set to
hidden:




mySubform.presence = "visible";



('mySubform' refers to the subform's correct SOM-expression)



In order to get the above code-fragment work, simply change it slightly into:




mySubform.presence = "visible";

this.caption.font.fill.color.value = this.caption.font.fill.color.value;



Which is rather silly indeed :-), but it works perfectly well.

 *sigh

Well, the workaround looks like it even works with any property. Like:




mySubform.presence = "visible";

this.presence = this.presence;



So you may use your favorite property...

Lol, well at least you found a usable workaround :P



Undoubtably this is a refresh bug. By changing a visibility property after changing the presence of the subform you're forcing a refresh. I'll get this logged as a bug in the system once I have a chance. Thanks for bring this to our attention.

I experinced something like you and solved it by refreshing the layout.. like this:



sub_extraInfo.presence = "visible";

xfa.layout.relayout();



I used a lot of time on this.. hope you don't
