Solution Model invalid form name runtime error in 5.1.1

Classic Servoy
1

I’m trying to use the solution model functions for the first time in servoy 5.1.1 and I put together a a small chunk of code in the onShow() event that seems to work except that I get an error the first time the cloned form is shown:

My code:

function onShow(firstShow, event)
{
// get an existing form
var form = solutionModel.getForm(‘frmwk_dbmaintenance_main’);
// make a clone/copy from it
var clone = solutionModel.cloneForm(‘clonedForm’, form);

// Create a first child form.
var childOne = solutionModel.newForm(‘childOne’, ‘bw’, ‘contact’, ‘null’, false, 400, 300);
childOne.newField(‘lastname’, JSField.TEXT_FIELD, 10, 10, 100, 20);
// Create a relation to link the parent form to the first child form.
var parentToChild = solutionModel.newRelation(‘parentToChild’,‘bw’,‘address’,‘bw’,‘contact’,JSRelation.INNER_JOIN);
parentToChild.newRelationItem(‘id’,‘=’,‘address’);
// Create a second child form.
var childTwo = solutionModel.newForm(‘childTwo’, ‘bw’, ‘contact’, ‘null’, false, 400, 300);
childTwo.newField(‘lastname’, JSField.TEXT_FIELD, 10, 10, 100, 20);
// Create a tab panel and add two tabs to it, with the two child forms.
var tabPanel = clone.getTabPanel(‘tabs_gridview’);
// var tabPanel = form.newTabPanel(‘tabs’, 100, 100, 300, 300);
tabPanel.newTab(‘tab1’, ‘Child One’, childOne, parentToChild); // The first form uses the relation.
tabPanel.newTab(‘tab2’, ‘Child Two’, childTwo);
}

The error:
name ‘clonedForm’ invalid for the clone of frmwk_dbmaintenance_main
Wrapped java.lang.RuntimeException: name ‘clonedForm’ invalid for the clone of frmwk_dbmaintenance_main (/Users/Chuck/bw_workspace/frmwk_dbMaintenance/forms/frmwk_dbmaintenance_main.js#86)
at /Users/Chuck/bw_workspace/frmwk_dbMaintenance/forms/frmwk_dbmaintenance_main.js:86 (onShow)

Other than the above, the cloned form looks right and has the additional tabs. It also seems to function fine after I dismiss the error. I’m sure whatever it is that I’m missing is very simple. Can anyone help?

Most likely the name “clonedForm” is already used for another form, because you have run this code before.

You need to check if the form already exists and remove it first:

  • Make sure it’s not visible
  • remove it from history (history.removeform(…))
  • Remove form from the solutionModel (solutionModel.removeForm(…))

Thanks Paul. I’ll try adding those steps and see if the error goes away
